So I have an AD8129 in my design, would there be an issue with powering the negative rail for 400mS longer than the positive rail during shut down. Were trying to figure out why they keep dieing on us. We have tried diodes across inputs with no luck. We our operating with a gain of 4.6, But stability doesn't seem to be the issue, my theory had been it was oscillating it's self to death but. Nether diodes or higher gain seems to work. Once the amp "Dies" it's noise output sky rockets.
