Overview
The PCM4202DBRG4, produced by Texas Instruments, is a high-performance, stereo audio analog-to-digital (A/D) converter designed for professional and broadcast audio applications. This component utilizes a 1-bit delta-sigma modulator per channel, incorporating a novel density modulated dither scheme to enhance dynamic performance. It supports 24-bit linear PCM output data with sampling frequencies up to 216kHz and can also output 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel.
