DESCRIPTION
The TLV320AIC3263 (also referred to as the AIC3263) is a flexible, highly-integrated, low-power, low-voltage
stereo audio codec. The AIC3263 features four digital microphone inputs, plus programmable outputs,
PowerTune capabilities, enhanced fully-programmable miniDSP, predefined and parameterizable signal
processing blocks, integrated PLL, and flexible digital 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.
