I made a high speed high side current sense using AD8000.
The PCB works as expected except it sometimes starts oscillation.
The oscillation starts at power up, but it could be stoped by shorting the outputs of two input stage AD8000s.
The circuit is based on a well-known high input impedance difference amp circuit. Two non-inverting AD8000s form a x100 gain stage and a x1 gain fully-differential OPA follow.
Can anybody help me to stop oscillation?
Could you post a schematic?
Thank you for your reply.
Please find the schematic.
