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 inter-

face, which supports standard audio data formats. Audio

data format selection, sampling mode configuration, and

high-pass filter functions are all programmed using dedi-

cated 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.
