DESCRIPTION
The TLV320AIC3212 (also referred to as the
AIC3212) is a flexible, highly-integrated, low-power,
low-voltage stereo audio codec. The AIC3212
features digital microphone inputs and programmable
outputs, PowerTune capabilities, selectable audio-
processing blocks, predefined and parameterizable
signal processing blocks, integrated PLL, and flexible
audio interfaces. Extensive register-based control of
power, input and output channel configuration, gains,
effects, pin-multiplexing and clocks are included,
allowing the device to be precisely targeted to its
application.
