TLV320AIC3109-Q1 Automotive Mono Audio Codecs Texas Instruments TLV320AIC3109-Q1 Automotive Low-Power 96kHz Mono Audio Codecs provides multiple input and output channels programmable in single-ended or fully differential configurations. The TLV320AIC3109-Q1 is ideal for low-power applications, offering extensive register-based power control which allows 48kHz digital-to-analog converter (DAC) playback at as little as 14mW consumption. The record path consists of 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). Audible noise is removed during record through programmable filters. MIX and MUX capability from the mono DAC and selected inputs, through programmable volume controls, to the various outputs are included in the playback path.
