Functional Description

3.2.2

Audio amplifier key features

q Very high PSRR micro bias reference due to bandgap from the 3.3V regulated supply, as well

as RC network for LF filtering in the audio bandwidth.

q Fully differential low-noise amplifier with gain control via serial IF (0dB to +42dB in 6dB steps).

Up to 1.8Vpp dynamic range on AUDOUTP and AUDOUTN
