SLLS544H–SEPTEMBER2002–REVISED JUNE2007 LOW-POWER DISSIPATION ADSL LINE DRIVER

?Low-Power Dissipation Increases ADSL Line The THS6182is a current feedback differential line Card Density driver ideal for full rate ADSL systems.Its extremely

low-power dissipation is ideal for ADSL systems that ?Low THD of-88dBc(100?,1MHz)

must achieve high densities in ADSL central office ?Low MTPR Driving+20dBm on the Line

rack applications.The unique architecture of the –-76dBc With High Bias Setting THS6182allows the quiescent current to be much

lower than existing line drivers while still achieving –-74dBc With Low Bias Setting

high linearity without the need for excess open loop ?Wide Output Swing of44V PP Differential Into

gain.Fixed multiple bias settings of the amplifiers a200-?Differential Load(V CC=±12V)

allow for enhanced power savings for line lengths ?High Output Current of600mA(Typ)where the full performance of the amplifier is not

required.To allow for even more flexibility and power ?Wide Supply Voltage Range of±5V to±15V

savings,an I ADJ pin is available to further lower the ?Pin Compatible with EL1503C and EL1508C

bias currents while maintaining stable operation with –Multiple Package Options as little as 1.8mA per channel.The wide output

swing of44V PP differentially with±12-V power ?Multiple Power Control Modes

supplies allows for more dynamic headroom,keeping –11mA/ch Full Bias Mode

distortion at a minimum.With a low 3.2nV/√Hz –7.5mA/ch Mid Bias Mode voltage noise coupled with a low10pA/√Hz inverting

–4mA/ch Low Bias Mode current noise,the THS6182increases the sensitivity

of the receive signals,allowing for better margins –0.25mA/ch Shutdown Mode

and reach.

(2)

For high-power dissipation applications,use of the PowerPAD package with the PowerPad on the underside of the chip.This acts as a heatsink and must be connected to a thermally dissipating plane for proper dissipation.Failure to do so may result in exceeding the maximum junction temperature which could permanently damage and/or reduce the lifetime the device.See TI technical brief SLMA002for more information about utilizing the PowerPAD thermally enhanced package.

(3)

Use of packages without the PowerPAD or not soldering the PowerPAD to the PCB,should be limited to low-power dissipation applications.

A.The PowerPAD is electrically isolated from all active circuity and pins.Connection of the PowerPAD to the PCB

ground plane is highly recommended,although not required,as this plane is typically the largest copper plane on a

PCB.The thermal performance will be better with a large copper plane than a small one.

THS6182

SLLS544H–SEPTEMBER 2002–REVISED JUNE 2007

The THS6182contains two independent operational amplifiers.These amplifiers are current feedback topology amplifiers made for high-speed operation.They have been specifically designed to deliver the full power requirements of ADSL and therefore can deliver output currents of at least 400mA at full output voltage.The THS6182is fabricated using Texas Instruments 30-V complementary bipolar process,HVBiCOM.This process provides excellent isolation and high slew rates that result in the device's excellent crosstalk and extremely low distortion.

The THS6182has a built-in thermal protection feature.Should the internal junction temperature rise above approximately 160°C,the device automatically shuts down.Such a condition could exist with improper heat sinking or if the output is shorted to ground.When the abnormal condition is fixed,the internal thermal shutdown circuit automatically turns the device back on.This occurs at approximately 145°C,junction temperature.Note that the THS6182does not have short-circuit protection and care should be taken to minimize the output current below the absolute maximum ratings.

The THS6182is available in a thermally-enhanced DWP and RHF package,which is a member of the PowerPAD family of packages.This package is constructed using a downset leadframe upon which the die is mounted [see Figure 69(a)and Figure 69(b),for the DWP package example].This arrangement results in the lead frame as a on the underside of the package [see Figure 69(c)].Because this thermal pad has direct thermal contact with the die,excellent thermal performance by providing a good thermal path away from the thermal pad.Note that the PowerPAD is electronically isolated from the active circuitry and any pins.Thus,the PowerPAD can be connected to any potential voltage within the absolute maximum voltage range.Ideally,connection of the PAD to the ground plane is preferred as the plane typically is the largest copper plane on a PCB.

The PowerPAD package allows for both assembly and thermal management in one manufacturing operation.During the surface-mount solder operation (when the leads are being soldered),the thermal pad can also be soldered to a copper area underneath the package.Through the use of thermal paths within this copper area,heat can be conducted away from the package into either a ground plane or other heat dissipating device.This is discussed in more detail in the PCB design considerations section of this document.

The PowerPAD package represents a breakthrough in combining the small area and ease of assembly of surface mount with the,heretofore,awkward mechanical methods of heatsinking.

A.The thermal pad is electrically isolated from all terminals in the package.

RECOMMENDED FEEDBACK AND GAIN RESISTOR VALUES OFFSET

VOLTAGE

NOISE CALCULATIONS

THS6182

SLLS544H–SEPTEMBER2002–REVISED JUNE2007

APPLICATION INFORMATION(continued)

As with all current feedback amplifiers,the bandwidth of the THS6182is an inversely proportional function of the value of the feedback resistor.The recommended resistors with a±12-V power supply for the optimum frequency response with a25-?load system is1k?for a gain of5.These should be used as a starting point and once optimum values are found,1%tolerance resistors should be used to maintain frequency response characteristics.

Consistent with current feedback amplifiers,increasing the gain is best accomplished by changing the gain resistor,not the feedback resistor.This is because the bandwidth of the amplifier is dominated by the feedback resistor value and internal dominant-pole capacitor.The ability to control the amplifier gain independently of the bandwidth constitutes a major advantage of current feedback amplifiers over conventional voltage feedback amplifiers.

It is important to realize the effects of the feedback resistance on distortion.Increasing the resistance decreases the loop gain and increases the distortion.It is also important to know that decreasing load impedance increases total harmonic distortion(THD).Typically,the third order harmonic distortion increases more than the second order harmonic distortion.

Finally,in a differential configuration as shown in Figure1,it is important to note that there is a differential gain and a common-mode gain which are different other.Differentially,the gain is at1+R F/R G.While common-mode gain=1due to R G being connected directly between each amplifier and not to ground.This can lead to potential problems as the stability of the amplifier is determined by R F.Thus,R F must be large enough to ensure the common-mode stability,even though a large differential gain may be required.

The output offset voltage,(V OO)is the sum of the input offset voltage(V IO)and both input bias currents(I IB) times the corresponding gains.The following schematic and formula can be used to calculate the output offset voltage:

Figure70.Output Offset Voltage Model

Noise can cause errors on very small signals.This is especially true for the amplifying small signals.The noise model for current feedback amplifiers(CFB)is the same as voltage feedback amplifiers(VFB).The only difference between the two is that the CFB amplifiers generally specify different current noise parameters for each input while VFB amplifiers usually only specify one noise current parameter.The noise model is shown in Figure71.This model includes all of the noise sources as follows:

?e n=Amplifier internal voltage noise(nV/√Hz)

?IN+=Noninverting current noise(pA/√Hz)

?IN-=Inverting current noise(pA/√Hz)

SLLS544H–SEPTEMBER 2002–REVISED JUNE 2007

APPLICATION INFORMATION (continued)

Figure 71.Noise Model

The total equivalent input noise density (e ni )is calculated by using the following equation:

To get the equivalent output noise of the amplifier,just multiply the equivalent input noise density (e ni )by the overall amplifier gain (A V ).

As the previous equations show,to keep noise at a minimum,small value resistors should be used.As the

closed-loop gain is increased (by reducing R G ),the input noise is reduced considerably because of the parallel resistance term.

Driving capacitive loads with high performance amplifiers is not a problem as long as certain precautions are taken.The first is to realize that the THS6182has been internally compensated to maximize its bandwidth and slew rate performance.When the amplifier is compensated in this manner,capacitive loading directly on the output will decrease the device's phase margin leading to high frequency ringing or oscillations.Therefore,for capacitive loads of greater than 10pF,it is recommended that a resistor be placed in series with the output of the amplifier,as shown in Figure 72.A minimum value of 2?should work well for most applications.For example,in 75-?setting the series resistor value to 75?both isolates any capacitance loading and provides the proper line impedance matching at the source end.

THS6182

SLLS544H–SEPTEMBER 2002–REVISED JUNE 2007

APPLICATION INFORMATION (continued)

Figure 72.Driving a Capacitive Load

Proper PCB design techniques in two areas are important to assure proper operation of the THS6182.These areas are high-speed layout techniques and thermal-management techniques.Because the THS6182is a high-speed part,the following guidelines are recommended.

?Ground plane -It is essential that a ground plane be used on the board to provide all components with a low inductive ground connection.Although a ground connection directly to a terminal of the THS6012is not necessarily required,it is recommended that the thermal pad of the package be tied to ground.This serves two functions.It provides a low inductive ground to the device substrate to minimize internal crosstalk and it provides the path for heat removal.Note that the BiCom process is a SOI process and thus,the substrate is isolated from the active circuitry.

?Input stray capacitance -To minimize potential problems with amplifier oscillation,the capacitance at the inverting input of the amplifiers must be kept to a minimum.To do this,PCB trace runs to the inverting input must be as short as possible,the ground plane should be removed under any etch runs connected to the inverting input,and external components should be placed as close as possible to the inverting input.This is especially true in the noninverting configuration.

?Proper power supply decoupling -Use a minimum of a 6.8-μF tantalum capacitor in parallel with a 0.1-μF ceramic capacitor on each supply terminal.It may be possible to share the tantalum among several amplifiers depending on the application,but a 0.1-μF ceramic capacitor should always be used on the supply terminal of every amplifier.In addition,the 0.1-μF capacitor should be placed as close as possible to the supply terminal.As this distance increases,the inductance in the connecting etch makes the capacitor less effective.The designer should strive for distances of less than 0.1inches between the device power terminal and the ceramic capacitors.

?For a differential configuration as shown in Figure 1,it is recommended that a 0.1-μF or 1-μF capacitor be added across the power supplies (from V CC+to V CC-)as close as possible to the THS6182.This allows for differential currents to flow properly,signficantly reducing even-order harmonic distortion.The 0.1-μF capacitors to ground should also be used as previously stipulated.Because of its power dissipation,proper thermal management of the THS6182is required.Although there are many ways to properly heatsink this device,the following steps illustrate one recommended approach for a multilayer PCB with an internal ground plane utilizing the 20pin DWP PowerPAD package.

1.Prepare the PCB with a top side etch pattern as shown in Figure 73.There should be etch for the leads as well as etch for the thermal pad.

2.Place 18holes in the area of the thermal pad.These holes should be 13mils in diameter.They are kept small so that solder wicking through the holes is not a problem during reflow.

3.It is recommended,but not required,to place six more holes under the package,but outside the thermal pad area.These holes are 25mils in diameter.They may be larger because they are not in the area to be soldered so that wicking is not a problem.

4.Connect all 24holes,the 18within the thermal pad area and the 6outside the pad area,to the internal ground plane.

5.When connecting these holes to the ground plane,do not use the typical web or spoke via connection methodology.Web connections have a high thermal resistance connection that is useful for slowing the

Vias should go through the board connecting the top layer

PowerPad to any and all ground planes. (The larger the ground

plane, the larger the area to distribute the heat.) Solder resist should be used on the bottom side ground plane in order to prevent wicking of the solder through the vias during the reflow process.

heat transfer during soldering operations.This makes the soldering of vias that have plane connections easier.However,in this application,low thermal resistance is desired for the most efficient heat transfer.Therefore,the holes under the THS6182package should make their connection to the internal ground plane with a complete connection around the entire circumference of the plated through hole.

6.The top-side solder mask should leave exposed the terminals of the package and the thermal pad area with its five holes.The four larger holes outside the thermal pad area,but still under the package,should be covered with solder mask.

7.Apply solder paste to the exposed thermal pad area and all of the operational amplifier terminals.

8.With these preparatory steps in place,the THS6182DWP is simply placed in position and run through the solder reflow operation as any standard surface-mount component.This results in a part that is properly installed.

二硫化碳危险特性及安全注意事项 详细版 提示语:本管理制度文件适合使用于日常的规则或运作模式中,包含所有的执行事项,并作用于规范个体行动,规范或限制其所有行为,最终实现简化管理过程,提高管理效率。,文档所展示内容即为所得,可在下载完成后直接进行编辑。 (一)危险特性 1、易燃性:易挥发出足以与空气形成可燃混和物的蒸汽,其着火所需能量极小,遇火、过热、流速过快以及和氧化剂接触等都有发生燃烧的危险。受热分解产生有毒的硫化物烟气。燃烧会产生一氧化碳、二氧化硫、二氧化碳等有毒气体,而且具有回燃的特点。 注:液体的闪点、沸点和自燃点越低,蒸汽压越大,发生着火燃烧的危险性也越大。 2、爆炸性:当挥发出的蒸汽与空气形成的混合气体达到爆炸极限浓度(1.3~50%)时,可燃混合物

就会转化成爆炸型混和物,一旦点燃就会发生爆炸。二硫化碳含量在(V%):4~8%时,爆炸威力最大,二硫化碳爆炸时的最大压力为730kpa (7.3atm)。 注:易燃液体的挥发性越强,爆炸下限越低,发生爆炸的危险性就越大。 3、流动扩散性:二硫化碳如果混入水中被排入下水系统,会在坑洼等地方积聚,从而增加了燃烧爆炸的危险性。 4、易产生或聚集静电:二硫化碳是电的不良导体,电阻率大,导电性差。在装卸运输过程中,因其所具有的流动性,可与不同性质的物体如容器壁和管道壁相互摩擦或接触时易积聚静电,静电积聚到一定程度时就会放电,产生静电放电火花而引起可燃性蒸汽混合物的燃烧爆炸。

二硫化碳危险特性及安全注意事项

工作行为规范系列 二硫化碳危险特性及安全 注意事项 (标准、完整、实用、可修改)

FS-QG-41130 编 号: 二硫化碳危险特性及安全注意事项 Dan gerous characteristics of carb on disulfide and safety precauti ons 说明:为规范化、制度化和统一化作业行为,使人员管理工作有章可循,提高工作效率和责任感、归属感,特此编写。 (一)危险特性 1、易燃性:易挥发出足以与空气形成可然混和物的蒸汽,其着火所需能量极小,遇火、过热、流速过快以及和氧化剂接触等都有发生燃烧的危险。而且具有回燃的特点。 注:液体的闪点、沸点和自然点越低,蒸汽压越大,发生着火燃烧的危险性也越大。 2、爆炸性:当挥发出的蒸汽与空气形成的混合气体达到爆炸极限浓度(1.3?50%)时,可燃混合物就会转化成爆炸型混和物,一旦点燃就会发生爆炸。 注:易燃液体的挥发性越强,爆炸下限越低,发生爆炸的 危险性就越大。 3、流动扩散性:二硫化碳如果混入水中被排入下水系统,会在坑

洼等地方积聚,从而增加了燃烧爆炸的危险性。 4、易产生或聚集静电:二硫化碳是电的不良导体,电阻率大,导电性差。在装卸运输过程中,因其所具有的流动性,可与不同性质的物体如容器壁和管道壁相互摩擦或接触时易积聚静电,静电积聚到一定程度时就会放电,产生静电放电火花而引起可燃性蒸汽混合物的燃烧爆炸。 5、毒害性:二硫化碳吸入后均能引起急、慢性中毒,损害神经系统等。 (二)安全注意事项 1、安全装卸: A、工作人员不准带火种、手机、手表、钥匙等金属物 B、必须穿戴好规定的防护用品,不准穿带贴定的鞋; C、二硫化碳运输车和水池内二硫化碳储罐进口连接时,要把导除静电的接地线连接好; D、开关阀门时,工具要轻拿轻放,以免撞出火花; E、开阀门时一定要注意,阀门要逐渐开大; F、做好消防准备工作,灭火器材处于战备状态。熟知掌握应急救援预案
