Overview
The PCM4204 is a high-performance, four-channel analog-to-digital (A/D) converter designed for professional and broadcast audio applications. It utilizes a 1-bit delta-sigma modulator per channel, incorporating a novel density modulated dither scheme for improved dynamic performance. The device supports 24-bit linear PCM output data with sampling frequencies up to 216kHz and can also be configured to output 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel.
