the tlv320aic3101 is a low-power stereo audio codec with stereo headphone amplifier, as well as multiple inputs and outputs that are programmable in single-ended or fully differential configurations. extensive register-based power control is included, enabling stereo 48-khz dac playback as low as 14 mw from a 3.3-v analog supply, making it ideal for portable battery-powered audio and telephony applications.

the record path of the tlv320aic3101 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (agc), with mix/mux capability among the multiple analog inputs. programmable filters are available during record which can remove audible noise that can occur during optical zooming in digital cameras.
