DESCRIPTION
The TLV320AIC3253 (sometimes referred to as the
AIC3253) is a flexible, low-power, low-voltage stereo
audio codec with digital microphone inputs and
programmable outputs, PowerTune capabilities,
fully-programmable miniDSP, fixed predefined and
parameterizable signal processing blocks, integrated
PLL, integrated LDO and flexible digital interfaces.
Extensive register-based control of power,
input/output channel configuration, gains, effects,
pin-multiplexing and clocks is included, allowing the
device to be precisely targeted to its application.
