Texas Instruments PCM9211PTR

Description

The PCM9211 is a complete analog and digital frontend for today's multimedia players, sound bars, 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)
