AFE General Purpose 1ADC 24-Bit 3.3V/5V 48-Pin LQFP Tray

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).
