art Number: OPA541
I'm using the OPA541 as a follower using a single supply,
I have a case during startup where the input is taken to the GND rail. However, the output shoots up to the positive rail. I'm assuming this is because of phase reversal.
I added diodes and a resistor to fix this, and it does somewhat. When the input goes to the GND rail the output at least goes down, although not all the way to the GND rail.
I've included some circuits and traces.
Do you any further guidance as to a protection circuit to use or other things that might happening with the part?
