Other Parts Discussed in Thread: INA138
1、It mainly does DC sampling, the front stage is a sampling resistor, and then detected by INA303, but the common mode voltage of INA303 is a little small, only 36V, the common mode voltage of the front input is as high as 120V, I want to string another 1KΩ resistor between the sampling resistor and INA303 to reduce the common mode voltage, is this scheme feasible, or is there another sampling method? Or other models recommended?
