3 Description
The TLV320AIC3262 (also referred to as the
AIC3262) is a flexible, highly-integrated, low-power,
low-voltage stereo audio codec. The AIC3262
features digital microphone inputs and programmable
outputs, PowerTune capabilities, enhanced fully-
programmable miniDSP, 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.
