DESCRIPTION
Digital Signal Processing and Noise
Filtering Available During Record
The TLV320AIC3106 is a low power stereo audio
codec with stereo headphone amplifier, 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.
•
•
Ten Audio Input Pins
–
Programmable in Single-Ended or Fully
Differential Configurations
–
3-State Capability for Floating Input
Configurations
Seven Audio Output Drivers
–
Stereo Fully Differential or Single-Ended
Headphone Drivers
The record path of the TLV320AIC3106 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.
