6630B Series Single-Output, 80-100 W GPIB Power SuppliesData SheetSpeed and accuracy for test optimizationThis series of linear-regulated 80-100 W DC power supplies is designed to max-imize the throughput of DUTs through the manufacturing test process. Both programming and measurement are optimized for speed. The active downprogrammer can sink up to the full rated current of the power supply, which quickly brings the power supply output to zero volts. The 6630B series offers many advanced programmable features including stored states and status reporting. Programming is done using industry standard SCPIcommands via the GPIB or RS-232. Test system integration is further simplified by using the VXI plug&play drivers. The optional relays simplify system design and troubleshooting.The optional front panel binding posts make the 6630B series convenient on the R&D lab bench. The built-in microamp measurement system helps the engineer to easily and accurately monitor the output voltage and currentwithout a complicated test setup.• Fast, low-noise outputs• Programmable active down-programmer sinks the full rated current • Dual-range, precision low current measurement • Optional isolation and polarity reversal relays• Built-in measurements and advanced programmable features • Protection features to ensure DUT safety 1981Specifications23Agilent Models: 6631B, 6632B 6633B, 6634BTopRearSupplemental characteristics for all model numbersDC floating voltage: Output terminals can be floated up to ± 240 VDC maximum from chassis ground Remote sensing: Up to two volts dropped in each load lead.

冷端补偿的K 型热电偶数字转换器（ 0 ℃至1024 ℃）MAX6675是一个复杂的热电偶数字转换器，带有一个内置的12位模拟数字转换器模数转换器（ADC）。

MAX6675还包含了冷结补偿传感和校正，数字控制器，一个SPI兼容接口，以及相关的控制逻辑。

在MAX6675的目的是一起工作的外部微控制器或其他情报，恒温，过程控制，或监测应用。

典型电路连线图温度转换在MAX6675包括信号调节硬件热电偶转换的信号转换成电压兼容与输入通道的模数转换器。

关热电偶作为一种主要的测温元件，具有结构简单。

制造容易。

使用方便。

测温范围宽。

测温精度高等特点。

但是将热电偶应用在基于单片机的嵌入式系统领域时，却存在着以下几方面的问题。

①非线性：热电偶输出热电势与温度之间的关系为非线性关系，因此在应用时必须进行线性化处理。

②冷补偿：热电偶输出的热电势为冷端保持为0℃时与测量端的电势差值，而在实际应用中冷端的温度是随着环境温度而变化的，故需进行冷端补偿。

③数字化输出：与嵌入式系统接口必然要采用数字化输出及数字化接口，而作为模拟小信号测温元件的热电偶显然法直接满足这个要求。

因此，若将热电偶应用于嵌入式系统时，须进行复杂的信号放大。

A/D转换。

查表线性线。

温度补偿及数字化输出接口等软硬件设计。

如果能将上述的功能集成到一个集成电路芯片中，即采用单芯片来完成信号放大。

冷端补偿。

线性化及数字化输出功能，则将大大简化热电偶在嵌入式领域的应用设计。

Maxim公司新近推出的MAX6675即是一个集成了热电偶放大器。

冷端补偿。

A/D转换器及SPI串口的热电偶放大器与数字转换器。

性能特点MAX6675的主要特性如下1、简单的SPI串行口温度值输出2、0℃～ 1024℃的测温范围3、片内冷端补偿4、高阻抗差动输入5、热电偶断线检测6、单一 5V的电源电压7、低功耗特性8、工作温度范围-20℃～ 85℃9、2000V的ESD信号该器件采用8引脚SO 帖片封装。

看门狗MAX705、706、813中文说明看门狗MAX705/706/8131 概述MAX705/706/813L是一组CMOS监控电路，能够监控电源电压、电池故障和微处理器(MPU或mP)或微控制器(MCU或mC)的工作状态。

将常用的多项功能集成到一片8脚封装的小芯片内，与采用分立元件或单一功能芯片组合的电路相比，大大减小了系统电路的复杂性和元器件的数量，显著提高了系统可靠性和精确度。

该系列产品采用3种不同的8脚封装形式：DIP、SO和mMAX。

主要应用于：微处理器和微控制器系统；嵌入式控制器系统；电池供电系统；智能仪器仪表；通信系统；寻呼机；蜂窝移动电话机；手持设备；个人数字助理(PDA)；电脑电话机和无绳电话机等等。

2 功能说明2.1 RESET/RESET操作复位信号用于启动或者重新启动MPU/MCU，令其进入或者返回到预知的循环程序并顺序执行。

一旦MPU/MCU处于未知状态，比如程序“跑飞”或进入死循环，就需要将系统复位。

对于MAX705和MAX706而言，在上电期间只要Vcc大于1.0V，就能保证输出电压不高于0.4V的低电平。

在Vcc上升期间RESET维持低电平直到电源电压升至复位门限(4.65V或4.40V)以上。

在超过此门限后，内部定时器大约再维持200ms后释放RESET，使其返回高电平。

无论何时只要电源电压降低到复位门限以下(即电源跌落)，RESET 引脚就会变低。

如果在已经开始的复位脉冲期间出现电源跌落，复位脉冲至少再维持140ms。

在掉电期间，一旦电源电压Vcc降到复位门限以下，只要Vcc不比1.0V还低，就能使RESET维持电压不高于0.4V 的低电平。

MAX705和MAX706提供的复位信号为低电平RESET，而MAX813L提供的复位信号为高电平RESET，三者其它功能完全相同。

有些单片机，如INTEL的80C51系列，需要高电平有效的复位信号。

2.2 看门狗定时器MAX705/706/813L片内看门狗定时器用于监控MPU/MCU的活动。

MAX3000中文资料General DescriptionThe MAX3000E/MAX3001E/MAX3002–MAX3012 8-channel level translators provide the level shifting neces-sary to allow data transfer in a multivoltage system.Externally applied voltages, V CC and V L , set the logic lev-els on either side of the device. Logic signals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa.The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012feature an EN input that, when low, reduces the V CC and V L supply currents to <2μA. The MAX3000E/MAX3001E also have ±15kV ESD protection on the I/O V CC side for greater protection in applications that route signals externally. The MAX3000E operates at a guaranteed data rate of 230kbps. The MAX3001E operates at a guaranteed data rate of 4Mbps. The MAX3002–MAX3012 operate at a guaranteed data rate of 20Mbps over the entire specified operating voltage range.The MAX3000E/MAX3001E/MAX3002–MAX3012 accept V L voltages from +1.2V to +5.5V and V CC voltages from +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The MAX3000E/MAX3001E/MAX3002–MAX3012 are available in 20-pin UCSP? and 20-pin TSSOP packages.ApplicationsCellphonesSPI? and MICROWIRE?

Externally applied voltages, V CC and V L , set the logic levels on either side of the device. Logicsignals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa.The MAX3000E/MAX3001E/MAX3002/MAX3003 are bidirectional level translators allowing data translation in either direction (V L ?V CC ) on any single data line.The MAX3004–MAX3012 unidirectional level translators level shift data in one direction (V L →V CC or V CC →V L ) on any single data line. The MAX3000E/MAX3001E/MAX3002–MAX3012 accept V L from +1.2V to +5.5V. All devices have V CC ranging from +1.65V to +5.5V, mak-ing them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012 feature an output enable mode that reduces V CC supply current to less than 2μA, and V L supply current to less than 2μA when in shutdown. The MAX3000E/MAX3001E have ±15kV E SD protection on the V CC side for greater protection in applications that route signals externally. The MAX3000E operates at a guaranteed data rate of 230kbps; the MAX3001E oper-ates at a guaranteed data rate of 4Mbps and the MAX3002–MAX3012 are guaranteed with a data rate of 20Mbps of operation over the entire specified operating voltage range.Level TranslationFor proper operation, ensure that +1.65V ≤V CC ≤+5.5V,+1.2V ≤V L ≤+5.5V, and V L ≤V CC . During power-up sequencing, V L ≥V CC does not damage th e device.During power-supply sequencing, when V CC is floating and V L is powering up, up to 10mA current can be sourced to each load on the V L side, yet the device does not latch up.The maximum data rate also depends heavily on the load capacitance (see the Typical Operating Characteristics ), outputimpedance of the driver, and the operational voltage range (see the Timing Characteristics ).Input Driver RequirementsThe MAX3001E/MAX3002–MAX3012 architecture is based on a one-shot accelerator output stage. See Figure 5. Accelerator output stages are always in three-state except when there is a transition on any of the translators on the input side, either I/O V L or I/O V CC .Then, a short pulse is generated during which the accel-erator output stages become active and charge/dis-charge the capacitances at the I/Os. Due to its bidirectional nature, both input stages become active during the one-shot pulse. This can lead to some current feeding into the external source that is driving the trans-lator. However, this behavior helps to speed up the tran-sition on the driven side.For proper operation, the driver has to meet the follow-ing conditions: 50?maximum output impedance and 20mA minimum output current (for 20Mbps versions),400?maximum output impedance and 4mA minimum output current (for 4Mbps versions), 1k ?maximum out-put impedance and 1mA minimum output current (for 230kbps versions). Figure 6 shows a typical input cur-rent vs. input voltage.Enable Output Mode (EN, EN A/B)The MAX3000E/MAX3001E/MAX3002 and the MAX3004–MAX3012 feature an EN input, and the MAX3003 has an EN A/B input. Pull EN low to set the MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012s ’ I/O V CC 1through I/O V CC 8 in three-state output mode, while I/O V L 1 through I/O V L 8 have internal 6k ?pulldown resis-tors. Drive EN to logic high (V L ) for normal operation. For the MAX3003,pull EN A/B low to place channels 1B through 4B in active mode, while channels 1A through 4A are in three-state mode. Drive EN A/B to logic high (V L ) to enable channels 1A through 4A, while channels 1B through 4B remain in three-state mode.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The I/O V CC lines have extra protection against static discharge. Maxim ’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, three-state output mode, and powered down. After an ESD event, Maxim ’s E versions keep working without latchup, whereas competing products can latch and must be powered down to remove latchup.ESD protection can be tested in various ways. The I/O V CC lines of the MAX3000E/MAX3001E are char-acterized for protection to ±15kV using the Human Body Model.M A X 3000E /M A X 3001E /M A X 3002–M A X 3012+1.2V to +5.5V , ±15kV ESD-Protected, 0.1μA,35Mbps, 8-Channel Level Translators 16__________________________________________________________________ ____________________ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 7a shows the Human Body Model and Figure 7b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the test device through a 1.5k ?resistor.Machine ModelThe Machine Model for ESD tests all pins using a 200pFstorage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protec-tion during manufacturing, not just inputs and outputs.Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Applications InformationPower-Supply DecouplingTo reduce ripple and the chance of transmitting incor-rect data, bypass V L and V CC to ground with a 0.1μF capacitor. T o ensure full ±15kV ESD protection, bypass V CC to ground with a 1μF capacitor. Place all capaci-tors as close to the power-supply inputs as possible.I 2C Level TranslationFor I 2C level translation for I 2C applications, please refer to the MAX3372E –MAX3379E/MAX3390E –MAX3393E datasheet.Unidirectional vs. Bidirectional LevelTranslatorThe MAX3000E/MAX3001E/MAX3002/MAX3003 can also be used to translate signals without inversion.These devices provide the smallest solution (UCSP package) for unidirectional level translation without inversion.Figure 5.
