Low Power Stereo Audio CODEC_2ADC1DAC

Overview

Innosilicon Codec is a low power, high resolution, stereo 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 Codec is suitable for applications in high end consumer digital audio systems, automobile audio, multimedia and digital systems.
