Low Power Mono Audio CODEC_1ADC1DAC

Overview

Innosilicon Audio Codec IP is a low power, high resolution, mono CODEC solution which employs Sigma-Delta noise-shaping technique. The ADC, DAC and power amplifier are integrated to provide total solutions. With 24-bit resolution for DAC and 24-bit resolution for ADC, Innosilicon Audio Codec is suitable for applications in high end consumer digital audio systems, automobile audio, multimedia, and digital systems.
