DESCRIPTION
–
–
92-dBA Signal-to-Noise Ratio
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.
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.
Supports Sample Rates From 8 kHz to 96
kHz

One Stereo Pair of Single-Ended Inputs
One Stereo Pair of Fully Differential Inputs
Six Audio Output Drivers
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. 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.
