GENERAL DESCRIPTION
The
ADAU1373
is a low power audio codec that supports stereo
record and playback. It provides eight single-ended or four
differential analog inputs with PGA for adjusting the gain. The
support for two stereo digital microphone inputs is provided so
that, in total, four digital microphones can be connected. In
addition, three serial digital audio in/out ports are provided
with ASRCs to support various sampling rates at the
input/output ports, allowing flexible system design.
The analog output side consists of line outputs, a headphone
output, a speaker output, and a receiver output. The two stereo
single-ended line level outputs are included, which can be
configured as two differential outputs. The headphone output is
stereo true-ground-centered with efficient Class-G architecture.
The efficient stereo filterless Class-D switching amplifier pro-
vides around 1 W stereo power for speakers. The differential
receiver amplifier can be used to connect the separate receiver
speaker.

. The board is featured
with USBi connection to the SigmaStudio™ graphical develop-
ment tool running on a host PC, which is used to program the
