The TLV320AIC3254 can help differentiate your designs for better audio quality, increased power control. The miniDSP off-loads the host processor to run complex algorithms such as noise and echo cancellation. PowerTune™ technology provides maximum flexibility to control power consumption. This codec's single-supply operation makes board design simpler and less expensive. The TLV320AIC3254 is supported by a PurePath™ Studio Development Toolkit to use pre-defined software as well as develop customized components.
