The TLV320AIC3104IRHBT is a Low-power Stereo Codec with 6 inputs, 6 outputs, HP amp and enhanced digital effects. Extensive register-based power control is included, enabling stereo 48kHz DAC playback as low as 14mW from a 3.3V analogue supply, making it ideal for portable battery-powered audio and telephony applications. The record path of contains integrated microphone bias, digitally controlled stereo microphone preamplifier and automatic gain control (AGC), with mix/mux capability among the multiple analogue inputs. Programmable filters are available during record which can remove audible noise that can occur during optical zooming in digital cameras. 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.
