Also you have mentioned that the op amp in the second stage gets damaged. Can you confirm that by testing that op amp in a buffer configuration(or any simple configuration) I am asking you to do this because we need to know if the part is actually failing or is it something else in the circuitry which is causing it to behave like this. I see. But

why the potential at V_SONIC_RX_BIAS2 is 1. 8V and at pin 7 is 2. 5V while the V_SONIC_RX is 3. 0V and why is this different from the op amp-A (1. 5V on bias voltage and pin 3 of op amp-A). u also see the photos in my previous emails when the op amp is in non-inverting configuration. op amp A vs op amp B. the output of op amp B is different from output of op amp A.
