3 Description
The TLV320AIC3109-Q1 device is a low-power mono
audio codec with a mono headphone amplifier and
multiple input and output channels that are
programmable in single-ended or fully differential
configurations. The device includes extensive
register-based power control, allowing 48-kHz digital-
to-analog converter (DAC) playback at as little as
14-mW consumption, making the device well-suited
for low-power applications.
The record path of the TLV320AIC3109-Q1 contains
integrated microphone bias, a digitally controlled
microphone preamplifier, automatic gain control
(AGC), a flexible front-end multiplexer (MUX), and a
front-end analog mixer (MIX). During record,
programmable filters can remove audible noise. The
playback path includes MIX and MUX capability from
the mono DAC and selected inputs, through
programmable volume controls, to the various
outputs.
