Hello, I want to use external audio op amp, OPA1622 of TI.
As in the attached photo, this opamp works using bipolar input.
So, please guide me how is that possible using the output of STM32G4 DAC.
Regards.

This DAC and op-amp pairing doesn't make any sense. OPA1622 is a very high performance op-amp. For high performance audio, the MCU's internal DAC is inadequate. For speech quality audio, the OPA1622 is an insane overkill.
