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.
