I want to purchase AD 844 current feed back operational amplifier, I have done simulation of a circuit which involves AD 844. Now I want to design that circuit but I am not sure How to feed current as an input in AD844.
AD844 require current as an input…
我在做电流发生器时，用到AD844 。 TZ管脚与2管脚电流相同，这个相同有什么限制条件？？以及2管脚和3管脚电压相等时的条件限制？？
I want to purchase AD 844 current feed back operational amplifier, But i am facing a problem while doing simulation part on PSPICE simulator. It is written in data sheet that in case of CFOA current at pin 5 Iz=+ or - of Ix.
With the help of AD 844…
Kind of cruising through the industry CFA datasheets for the better DC error ones for this next PlanetAnalog article - There was more effort than usual in the old AD844 datasheet, which is nice, but I happened to notice looking down a bit further there…
按照上图进行电路搭建后（R=1.5k，电源电压±15V，Uout输出所接RC分别为1.5K和0.1uF），Uin输入8KHz，1.5V的正弦信号，希望输出幅值1mA的正弦恒流源，但实际测试发现，低负载状况下（ZL<5K），线性度较好，当负载大于5K时，实际幅度<ZL*1mA，（10K负载时，实际输出只有9V），为何？理论上不是应该等于ZL*1mA么？analogchina-adminFormerMemberhdx2FormerMemberAnalog1ezchinatest112…
为什么pspice中的AD844只能放大到400mV左右，官网的spice模型也是400mV左右，实际中易震荡了，放大倍数又是提不上去，有没有好的方法来解决这个问题呢，是不符合稳定条件，还是电源耦合，也可能去耦不好，头快炸了，总之是见鬼了，有没有lBOARD LAYOUT参考啊，请教大家，小弟不胜感激
下图是个仿真例子，另外那个过冲怎么回事啊
AD844的第5pin是用来做补偿的，尤其是在驱动容性负载的时候需要添加RC做补偿，保证输出的稳定性。补偿端加220nF的电容可能确实太大了，而且电容接地是否合适呢，另外pin5的电阻接地是有何用意呢？请仔细阅读AD844的datasheet再做电路设计。
we can implement second generation current conveyors with 3 pins of AD844s'. Also i attached the figure of implementation of Differential voltage Current Conevyor with commercialy AD844AN ICs. I want to know about any possible model of Fully deferential…
AD844可以单电源供电吗，我想用他做一个恒流源电路，+5V和地给他供电，没有负电压可以吗
AD817的驱动能力比AD844强，而且AD844驱动大电容性负载需要外接RC，其它特性基本差不多，谢谢回复， ！
