The TLV320AIC32IRHBT is a low-power stereo Audio Codec with a 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 48kHz DAC playback as low as 14mW from a 3.3V analog supply, making it ideal. The record path of the codec contains integrated microphone bias, digitally-controlled stereo-microphone pre-amp and automatic gain control, with mix/mux capability among the multiple analog inputs. The playback path includes mix/mux capability from the stereo DAC and selected inputs, through programmable volume controls, to the various outputs. It contains four high-power output drivers as well as two fully differential output drivers.
