The CS4207 is a highly integrated multi-channel low power HD audio codec featuring 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIF transmitter and receiver, microphone preamp and bias voltage, and a ground centered headphone driver. Based on multibit, Delta Sigma modulation, it allows infinite sample rate adjustment between 32 kHz and 192 kHz.
The ADC input path allows control of a number of features. The microphone input path includes a selectable programmable-gain pre-amplifier stage and a low noise MIC bias voltage supply. A GA is available for line and microphone inputs and provides analog gain with soft ramp and zero cross transitions. The ADC also features an additional digital volume attenuator with soft ramp transitions.
