3 Description
The TLV320AIC3104-Q1 is a low-power stereo audio
codec with stereo headphone amplifiers, 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 car
audio applications in cluster and head unit systems.
The record path of the TLV320AIC3104-Q1 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 noisy and unpredictable
environments, such as when an e-call system
is activated. The playback path includes mix/mux
capability from the stereo DAC and selected inputs,
through programmable volume controls, to the various
outputs.
