TLV320AIC3105
SLAS513C –FEBRUARY 2007–REVISED DECEMBER 2014
TLV320AIC3105 Low-Power Stereo Audio Codec for Portable Audio and Telephony
1 Features
3 Description
The TLV320AIC3105 is a low-power stereo audio
codec with multiple single-ended inputs and a stereo
headphone amplifier. The output stages 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.

Stereo Audio ADC
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, through
programmable volume controls, to the various
outputs.
