3 Description

The TLV320AIC3106-Q1 is a low-power stereo audio codec with stereo headphone amplifier, as well as multiple inputs and outputs programmable in single-ended or fully differential configurations. Extensive register-based power control is included, enabling stereo 48-kHz DAC playback as low as 15 mW from a 3.3-V analog supply, making it ideal for car audio applications in cluster and head unit systems.

The record path of the TLV320AIC3106-Q1 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix and mux capability among the multiple analog inputs. Programmable filters are available during record which can remove audible noise that can occur in unpredictable environments, such as when an eCall system is activated. The playback path includes mix and mux capability from the stereo DAC and selected inputs, through programmable volume controls, to the various outputs.
