Hi, Ravi,

The TPA6138A2 can be used with the PCM1789, but you need to make sure the output signal of the DAC is conditioned to make it compliant with the recommended operating conditions of the amplifier inputs.

Hi, Ravi,

The TPA6138A2 has a TINA TI model for simulation, but unfortunately, the PCM1789 doesn't have it.
