5.20.3
The headphone amplifier boosts the power from the DAC and drives the headphone. It also provides analog volume control to
optimize the noise performance of the entire channel.
5.20.4
The microphone amplifier boosts the signal from the microphone and provides it to the ADC. The gain control present in the
microphone amplifier helps in optimizing the noise performance of the entire channel.
