24bit Audio ADC/24bit Video DAC, SMIC 55LL
The Innosilicon Codec is a low power, high resolution, single-chip stereo CODEC that employs the high order Sigma-Delta noise shaping technique. The ADC, DAC and power amplifier are integrated to provide total solutions. With 24bit resolution for DAC and 18 bit resolution for ADC, this IP is suitable for applications in consumer digital audio systems, automobile audio, multimedia and digital systems. The key feature is high performance, low power and low cost.
