DESCRIPTION
The TLV320AIC3107 is a low power stereo audio
codec with stereo headphone amplifier, and mono
class-D speaker driver, as well as multiple inputs and
outputs programmable in single-ended 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 TLV320AIC3107 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.
The TLV320AIC3107 contains three high-power
output drivers as well as two single-ended line output
drivers, and a differential class-D output driver.
