The PCM9211 is a complete analog and digital front-end for today's multimedia players and recorders.

The PCM9211 integrates a stereo ADC, S/PDIF transceiver with up to 12 multiplexed inputs and 3x PCM inputs to allow other audio receivers to be multiplexed along with the analog and S/PDIF signals to a digital signal processor (DSP).
