3 Description

The TLV320AIC3106 is a low-power stereo audio

codec with stereo headphone amplifier, as well as

multiple inputs and outputs programmable in singleended

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 portable

battery-powered audio and telephony applications.

The record path of the TLV320AIC3106 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.
