The output stages are programmable in single-ended or fully differential configurations. Extensive register-based power control is included, enabling stereo 48-k Hz DAC playback as low as 14 m W from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications. The record path of the TLV320AIC3105 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. The playback path includes mix/mux capability from the stereo DAC and selected inputs,...
