Texas Instruments PCM9211 Audio Interface Transceivers

Texas Instruments PCM9211 Audio Interface Transceivers are complete analog and digital front-end solutions for today's multimedia players and recorders. The TI PCM9211 integrates a stereo analog-to-digital converter, 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. These TI audio interface transceivers are designed for use in home theaters and AVR equipment, television and soundbars, high-performance sound cards, and more.
