3 Description
The TLV320AIC3104 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. The
device includes extensive register-based power
control is included, thus enabling stereo 48-kHz DAC
playback as low as 14 mW from a 3.3-V analog
supply, making the device ideal for portable battery-
powered audio and telephony applications.
The record path of the TLV320AIC3104 contains
integrated microphone bias, digitally controlled stereo
microphone preamplifier, and automatic gain control
(AGC), with mix/mux capability among the multiple
analog inputs. During record, programmable filters
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.
