  • OPA928: root-causing failed OPA928 in TIA and protecting inputs against exceeding absolute maximum ratings

    Part Number: OPA928 Hi team As I understand it, the OPA928 absolute maximum ratings are +/-0.5V for differential voltage at input and +/-10mA through an input pin. We have an autoranging TIA design where one OPA928 failed during testing. This failure…
