Overview
The PCM4204PAPR is a high-performance, four-channel analog-to-digital (A/D) converter designed by Texas Instruments 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 1-bit direct stream digital (DSD) data in 64x or 128x oversampled modes. The PCM4204PAPR is versatile, supporting both PCM and DSD data formats, making it suitable for various digital audio recording and processing applications.
