TLV320AIC3109-Q1 - Automotive Low-Power 96kHz Mono Audio Codec

The TLV320AIC3109-Q1 device is a low-power mono audio codec with a mono headphoneamplifier and multiple input and output channels that are programmable in single-ended or fullydifferential configurations. The device includes extensive register-based power control, allowing48-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 digitallycontrolled 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 audiblenoise. The playback path includes MIX and MUX capability from the mono DAC and selected inputs,through programmable volume controls, to the various outputs.
