TLV320AIC3254 Low-Power 1.8 Audio Codec

Produce feature-rich consumer electronics products with better audio quality and longer battery life with the TLV320AIC3254

Image of Texas Instruments' TLV320AIC3254 Audio CodecThe 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 that a device can be set for very low power and good signal-to-noise ratio (SNR) or low power and very good SNR. The codec's single-supply operation makes audio design easier as well as less expensive.
