Have you heard? Low-power 1.8V audio codec with miniDSP The TLV320AIC3254 is a low-power audio codec with an integrated miniDSP, PowerTune™ technology and single-supply operation. The miniDSP off-loads the host processor and allows users to run complex algorithms such as noise and echo cancellation. PowerTune technology provides maximum flexibility for power consumption control. This control means a device can be set for very low power and good signal-to-noise ratio (SNR) or low power and very good SNR. And, the codec's single-supply operation makes audio design easier as well as less expensive. The TLV320AIC3254 comes with a PurePath™ Studio Development Toolkit that enables the use of predefined software as well as the ability to develop customized components. Order TLV320AIC3254 samples!
