I found and resolved the problem,
It wasn't AD5445
It wasn't LTC6078
It wasn't OP2177
Assembly house rotate two resistors and effectively short two grounds, but it wasn't completely short, it was just enough to mess-up things,
THANK…
Thanks for the reply
yes I am using the cables,
We are trying to replicate a lab based potentiostsat experiment on an embedded device.
the sensor used is a prototype with two electrodes for water sample analysis
A cyclic voltammetry scan is used to observe…
您好！
由于学术需要，我需要几款已知沟道长度的CMOS运算放大器，但在所有的运放的手册里都查不到相关信息，这导致我的课题无法进行下去，希望能够得到帮助。我只需要获得几款CMOS运放和他们相应的沟道长度信息，只要有三种不同沟道长度的运放芯片即可（最好增益带宽积相差不大）。或者请告诉我AD8655， LTC6088， LTC6087， LTC6078/9系列的CMOS沟道长度，谢谢！
恳请您的回复，谢谢！
