Hi again. krisf can ı ask you another question. When ı read op177 datasheet and ı see typical offset voltage is 40 uV but ı set up test circuit my offset voltage 5 mV. Maybe this is a problem. What can ı do for this.
what is Y1 in your schematic. I do not follow exactly what you are doing but you can look at figure 36 of OP77 datasheet hwich gives you detection and amplification. You may need to do adjustment for your needs.
We are using AD624 Instrumentation Amplifier for our signal Conditioning Application for Strain gauge based sensor like Force and Torque Sensors. Here we get Voltage in mV and we are using AD624 as IA and then a second order Butter worth filter…

1、在运算放大器应用技术手册（OP AMP APPLICATIONS HANDBOOK）及OP177的手册中写到OP177的开环增益非线性的测试电路如下图：

图 2 开环增益非线性度的SPICE模型仿真电路
图 3 V-Vx，V-Vy的仿真结果
I think this is very simply explained. I know that any type of analysis consists of successive stages. When running any type of analysis, the first step is always to search for a DC operating point, for example.
These steps can be canceled…
We have a task to measure a current range from 1uA to 300mA. The measurements must be completed without switching the range with a BW of 250kHz.
The proposed solution is:
