Low Power Audio CODEC/ADC/DAC
Low Power Audio
Innosilicon Audio CODEC IP consists of ADC channels, DAC channels and bias circuit. The ADC channel is used to convert analog audio signal to digital signal. Each ADC channel contains input PGA, ALC, Sigma-Delta modulator and digital filter. The DAC channel is used to convert digital audio signal to analog signal. Each DAC channel contains Sigma-Delta modulator, DCT and power amplifier. The bias circuit generates voltage and current reference.
