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.
