JeffRowland的基于LM3886、TDA7293的功放跻身世界优秀功放之林，更证明了功率IC本身性能之优异。

虽然JeffRowland证明了功率IC可以好声，而且这些IC家喻户晓，使用者众多，但“IC音质不如分立元件”的观念却依然根深蒂固的扎根于广大DIY发烧友的头脑里。

很多人对这些芯片的认识来自未能发挥芯片的制作，造成对这些芯片的误解。

本文将从产品数据手册入手，多角度，深入地挖掘产品数据手册中包含的丰富信息，揭开数据背后隐藏的秘密，以求给大家一个全面的认识。

1． LM1875LM1875是美国国家半导体公司20世纪90年代初推出的一款音频功放IC，如图1所示。

HBR110特定人语音识别处理器芯片说明北京承芯卓越科技有限公司Beijing Helios-ADSP Technology Co. Ltd., All Rights Reserved.(Buzzer)A PP P P P P P P P(0,0)DIE PAD Ring上图为芯片内建平衡放大器(Equalizer Amplifier)的示意图及连接方法，其中C L，R L，为芯片的外围阻容器件。

图示电路可实现AUDIO_L和AUDIO_R两路信号的混合放大及滤波，其输出可直接连接AMP_IN。

对于绝大多数应用，AUDIO_L，AUDIO_R两路无须同时使用，仅需连接即可，此时，C R，R R可以省略。

SEATING PLANE最小80.711.97上图所示为最简单的非特定人语音识别系统，除芯片周边的简单阻容器件外，只需外接SPI Flash及简单音频放大电路(蓝色线框内)。

图中按键为复位键，指示灯D1可指示芯片的工作状态及是否检测到语音，系统上电或复位后，指示灯会持续点亮，表明系统正进行初始化，此后指示灯熄灭，如果模型未训练，系统进入训练状态，否则进入识别状态。

在训练或识别状态下，每当芯片检测到语音或噪声存在时，指示灯就会点亮。

为提高识别率，用户应在指示灯灭时(表明无其他语音或噪声的存在)，才开始命令语句，以保证芯片检测到正确有效的语音内容。

2.主从工作系统对于某些复杂应用(如语音控制PDA)，主控芯片可独立完成各类控制及显示任务，其所需的，仅是在系统中加入一个语音识别协处理模块，用于辨识输入语音并播放应答句；主控芯片往往需要协处理模块回传识别结果，并根据识别结果进行控制或显示；主控芯片只在需要训练或识别时开启协处理模块，不需要时，则关闭协处理模块以降低功耗。

这样的语音识别协处理模块，可以使用HBR110来构建。

下图为使用HBR110构建主从工作系统的连接示意图。

HBR110可通过P14和P16将工作状态及识别结果串行输出给主控芯片，主控芯片对HBR110的控制则通过P00、P04、P05、P06实现，当屏蔽P06。

主流发烧运放IC的介绍兼评七款电压反馈型双运放运算放大器是运用得非常广泛的一种线性集成电路。

而且种类繁多，在运用方面不但可对微弱信号进行放大，还可做为反相、电压跟随器，可对电信号做加减法运算，所以被称为运算放大器。

不但其他地方应用广泛，在音响方面也使用得最多。

例如前级放大、缓冲，耳机放大器除了有部分使用分立元件，电子管外，绝大部分使用的还是集成运算放大器。

而有时候还会用到稳压电路上，制作高精度的稳压滤波电路。

各种运放由于其内部结构的不同，产生的失真成分也不同，所以音色特点也有一定的区别。

本来我们追求的是高保真，运放应该是失真最低，能真实还原音乐，没有个性的最好。

但是由于要配合其他音响部件如数码音源、后级功放管等如果偏干、偏冷则可搭配音色细腻温暖型的运放，而太过阴柔、偏软的则可搭配音色较冷艳、亮丽的运放，做到与整机配合，取长补短的最佳效果。

所以说并不是选择越贵的运放得到的效果就一定越好，搭配很重要，达到听感上最好才算达到目的。

如果是应用在低电压的模拟滤波电路中，还要选择对低电压工作性能良好的运放种类。

市面上的运放种类不下五六百种，GBW带宽在5M以上的也有三百多种，最高的已达300MHZ，转换速率在5V/us以上的也不下几百种，最高达3000V/us。

以上介绍的几种被音响发烧友们炒得火热的，其实还有大量未被大家熟知的上乘佳品可供选择，大家不必局限于以上几种。

一种运放型号的封装也可分为金封、陶封和塑封，一般来说金封、陶封的质量较好，塑封的品质稍差。

利益的驱使，什么都有假货，运放也不例外，市面上的假货不少，如果想便宜捡好货，那就要慧眼识珠了，不太在行的在购买时就要注意，宁可多花一块几毛，也要到信誉较好的商家去买。

低档运放JRC4558。

这种运放是低档机器使用得最多的。

现在被认为超级烂，因为它的声音过于明亮，毛刺感强，所以比起其他的音响用运放来说是最差劲的一种。

不过它在我国暂时应用得还是比较多的,很多的四、五百元的功放还是选择使用它，因为考虑到成本问题和实际能出的效果,没必要选择质量超过5532以上的运放。

Application Frequency Response1012764810127649L M 4808 12Application InformationEXPOSED-DAP PACKAGE PCB MOUNTING CONSIDERATIONThe LM4808’s exposed-dap(die attach paddle)package (LD)provides a low thermal resistance between the die and the PCB to which the part is mounted and soldered.This allows rapid heat transfer from the die to the surrounding PCB copper traces,ground plane,and surrounding air. The LD package should have its DAP soldered to a copper pad on the PCB.The DAP’s PCB copper pad may be con-nected to a large plane of continuous unbroken copper.This plane forms a thermal mass,heat sink,and radiation area. However,since the LM4808is designed for headphone ap-plications,connecting a copper plane to the DAP’s PCB copper pad is not required.The LM4808’s Power Dissipation vs Output Power Curve in the Typical Performance Char-acteristics shows that the maximum power dissipated is just 45mW per amplifier with a5V power supply and a32Ωload. Further detailed and specific information concerning PCB layout,fabrication,and mounting an LD(LLP)package is available from National Semiconductor’s Package Engineer-ing Group under application note AN1187.POWER DISSIPATIONPower dissipation is a major concern when using any power amplifier and must be thoroughly understood to ensure a successful design.Equation1states the maximum power dissipation point for a single-ended amplifier operating at a given supply voltage and driving a specified output load.P DMAX=(V DD)2/(2π2R L)(1)Since the LM4808has two operational amplifiers in one package,the maximum internal power dissipation point is twice that of the number which results from Equation1.Even with the large internal power dissipation,the LM4808does not require heat sinking over a large range of ambient tem-perature.From Equation1,assuming a5V power supply and a32Ωload,the maximum power dissipation point is40mW per amplifier.Thus the maximum package dissipation point is80mW.The maximum power dissipation point obtained must not be greater than the power dissipation that results from Equation2:P DMAX=(T JMAX−T A)/θJA(2)For package MUA08A,θJA=210˚C/W.T JMAX=150˚C for the LM4808.Depending on the ambient temperature,T A,of the system surroundings,Equation2can be used to find the maximum internal power dissipation supported by the IC packaging.If the result of Equation1is greater than that of Equation2,then either the supply voltage must be de-creased,the load impedance increased or T A reduced.For the typical application of a5V power supply,with a32Ωload, the maximum ambient temperature possible without violating the maximum junction temperature is approximately133.2˚C provided that device operation is around the maximum power dissipation point.Power dissipation is a function of output power and thus,if typical operation is not around the maximum power dissipation point,the ambient temperature may be increased accordingly.Refer to the Typical Perfor-mance Characteristics curves for power dissipation infor-mation for lower output powers.POWER SUPPLY BYPASSINGAs with any power amplifier,proper supply bypassing iscritical for low noise performance and high power supplyrejection.Applications that employ a5V regulator typicallyuse a10µF in parallel with a0.1µF filter capacitors to stabi-lize the regulator’s output,reduce noise on the supply line,and improve the supply’s transient response.However,theirpresence does not eliminate the need for a local0.1µFsupply bypass capacitor,C S,connected between theLM4808’s supply pins and ground.Keep the length of leadsand traces that connect capacitors between the LM4808’spower supply pin and ground as short as possible.Connect-ing a1.0µF capacitor,C B,between the IN A(+)/IN B(+)nodeand ground improves the internal bias voltage’s stability andimproves the amplifier’s PSRR.The PSRR improvementsincrease as the bypass pin capacitor value increases.Toolarge,however,increases the amplifier’s turn-on time.Theselection of bypass capacitor values,especially C B,dependson desired PSRR requirements,click and pop performance(as explained in the section,Selecting Proper ExternalComponents),system cost,and size constraints.SELECTING PROPER EXTERNAL COMPONENTSOptimizing the LM4808’s performance requires properly se-lecting external components.Though the LM4808operateswell when using external components with wide tolerances,best performance is achieved by optimizing component val-ues.The LM4808is unity-gain stable,giving a designer maximumdesign flexibility.The gain should be set to no more than agiven application requires.This allows the amplifier toachieve minimum THD+N and maximum signal-to-noise ra-tio.These parameters are compromised as the closed-loopgain increases.However,low gain demands input signalswith greater voltage swings to achieve maximum outputpower.Fortunately,many signal sources such as audioCODECs have outputs of1V RMS(2.83V P-P).Please refer tothe Audio Power Amplifier Design section for more infor-mation on selecting the proper gain.Input and Output Capacitor Value SelectionAmplifying the lowest audio frequencies requires high valueinput and output coupling capacitors(C I and C O in Figure1).A high value capacitor can be expensive and may compro-mise space efficiency in portable designs.In many cases,however,the speakers used in portable systems,whetherinternal or external,have little ability to reproduce signalsbelow150Hz.Applications using speakers with this limitedfrequency response reap little improvement by using highvalue input and output capacitors.Besides affecting system cost and size,C i has an effect onthe LM4808’s click and pop performance.The magnitude ofthe pop is directly proportional to the input capacitor’s size.Thus,pops can be minimized by selecting an input capacitorvalue that is no higher than necessary to meet the desired−3dB frequency.As shown in Figure1,the input resistor,R I and the inputcapacitor,C I,produce a−3dB high pass filter cutoff fre-quency that is found using Equation(3).In addition,theoutput load R L,and the output capacitor C O,produce a-3dbhigh pass filter cutoff frequency defined by Equation(4).f I-3db=1/2πR I C I(3)f O-3db=1/2πR L C O(4)LM480813Application Information(Continued)Also,careful consideration must be taken in selecting acertain type of capacitor to be used in the system.Differenttypes of capacitors(tantalum,electrolytic,ceramic)haveunique performance characteristics and may affect overallsystem performance.Bypass Capacitor ValueBesides minimizing the input capacitor size,careful consid-eration should be paid to the value of the bypass capacitor,C B.Since C B determines how fast the LM4808settles toquiescent operation,its value is critical when minimizingturn-on pops.The slower the LM4808’s outputs ramp to theirquiescent DC voltage(nominally1/2V DD),the smaller theturn-on pop.Choosing C B equal to 1.0µF or larger,willminimize turn-on pops.As discussed above,choosing C i nolarger than necessary for the desired bandwith helps mini-mize clicks and pops.AUDIO POWER AMPLIFIER DESIGNDesign a Dual70mW/32ΩAudio AmplifierGiven:Power Output70mWLoad Impedance32ΩInput Level1Vrms(max)Input Impedance20kΩBandwidth100Hz–20kHz±0.50dBThe design begins by specifying the minimum supply voltagenecessary to obtain the specified output power.One way tofind the minimum supply voltage is to use the Output Powervs Supply Voltage curve in the Typical Performance Char-acteristics section.Another way,using Equation(5),is tocalculate the peak output voltage necessary to achieve thedesired output power for a given load impedance.To ac-count for the amplifier’s dropout voltage,two additional volt-ages,based on the Dropout Voltage vs Supply Voltage in theTypical Performance Characteristics curves,must beadded to the result obtained by Equation(5).For asingle-ended application,the result is Equation(6).(5)V DD≥(2V OPEAK+(V ODTOP+V ODBOT))(6)The Output Power vs Supply Voltage graph for a32Ωloadindicates a minimum supply voltage of4.8V.This is easilymet by the commonly used5V supply voltage.The additionalvoltage creates the benefit of headroom,allowing theLM4808to produce peak output power in excess of70mWwithout clipping or other audible distortion.The choice ofsupply voltage must also not create a situation that violatesmaximum power dissipation as explained above in thePower Dissipation section.Remember that the maximumpower dissipation point from Equation(1)must be multipliedby two since there are two independent amplifiers inside thepackage.Once the power dissipation equations have beenaddressed,the required gain can be determined from Equa-tion(7).(7)Thus,a minimum gain of1.497allows the LM4808to reachfull output swing and maintain low noise and THD+N perfro-mance.For this example,let A V=1.5.The amplifiers overall gain is set using the input(R i)andfeedback(R f)resistors.With the desired input impedanceset at20kΩ,the feedback resistor is found using Equation(8).A V=R f/R i(8)The value of R f is30kΩ.The last step in this design is setting the amplifier’s−3dbfrequency bandwidth.To achieve the desired±0.25dB passband magnitude variation limit,the low frequency responsemust extend to at lease one−fifth the lower bandwidth limitand the high frequency response must extend to at least fivetimes the upper bandwidth limit.The gain variation for bothresponse limits is0.17dB,well within the±0.25dB desiredlimit.The results are anf L=100Hz/5=20Hz(9)and af H=20kHz*5=100kHz(10)As stated in the External Components section,both R i inconjunction with C i,and C o with R L,create first order high-pass filters.Thus to obtain the desired low frequency re-sponse of100Hz within±0.5dB,both poles must be takeninto consideration.The combination of two single order filtersat the same frequency forms a second order response.Thisresults in a signal which is down0.34dB at five times awayfrom the single order filter−3dB point.Thus,a frequency of20Hz is used in the following equations to ensure that theresponse is better than0.5dB down at100Hz.C i≥1/(2π*20kΩ*20Hz)=0.397µF;use0.39µF.C o≥1/(2π*32Ω*20Hz)=249µF;use330µF.The high frequency pole is determined by the product of thedesired high frequency pole,f H,and the closed-loop gain,A V.With a closed-loop gain of1.5and f H=100kHz,theresulting GBWP=150kHz which is much smaller than theLM4808’s GBWP of900kHz.This figure displays that if adesigner has a need to design an amplifier with a highergain,the LM4808can still be used without running intobandwidth limitations.LM48814Demonstration Board Layout10127639Recommended SO PC Board Layout:Top
