Texas Instruments PCM4222PFBR

Description
The PCM4222 is a high-performance, two-channel, 24-bit, 216kHz sampling multi-bit delta-sigma analog-to-digital converter. It supports linear PCM, 1-bit Direct Stream Digital (DSD), and multi-bit modulator output data. The PCM4222 features differential voltage inputs, an on-chip voltage reference, and low power dissipation.
