  • OPA992-Q1: If I do not power the OP-AMP, is it safe for current to flow through Vin- and Vo?

    TI Thinks Resolved
    Part Number: OPA992-Q1 Here is my TIA circuit Since this circuit has high feedback resistor (100Meg) for OP-AMP, Vo would be about 300mV when power off due to environment light, and Vo would be about 100 mV when power on due to 0.1 bias of V+…
