118dB SNR Stereo Audio ADC - PCM4202

PCM4202 (ACTIVE)

118dB SNR Stereo Audio ADC

 

Description

The PCM4202 is a high-performance, stereo audio analog-to-digital (A/D) converter designed for professional and broadcast audio applications. The PCM4202 architecture utilizes a 1-bit delta-sigma modulator per channel, incorporating a novel density modulated dither scheme for improved dynamic performance.

The PCM4202 supports 24-bit linear PCM output data, with sampling frequencies up to 216kHz. The PCM4202 can also be configured to output either 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel. Support for PCM and DSD output formats makes the PCM4202 suitable for a variety of digital audio recording and processing applications.

The PCM4202 includes a flexible audio serial port interface, which supports standard audio data formats. Audio data format selection, sampling mode configuration, and high-pass filter functions are all programmed using dedicated control pins.

The PCM4202 operates from a +5V analog power supply and a +3.3V digital power supply. The digital I/O pins are compatible with +3.3V logic families. The PCM4202 is available in a small SSOP-28 package.
