Other Parts Discussed in Thread: INA240-SEP, INA190
Hi,
I'm designing a high voltage board which has a voltage output around 400VDC. I also need to monitor the current and my load will draw about 60 micro amp. I found TI Circuit Note SBOA295_June 2018 (High-voltage, high-side floating current sensing circuit using current output, c ) and planning to follow it to sense current on high voltage.
I'm looking for Rad-Hard current sensing IC that can sense current in micro amp range. I simulated INA901-SP before and did not think it would work in micro amp range. Do you have any rad-hard amplifier that can sense current in micro amp range? Thanks
