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 216 kHz. The PCM4202

can also be configured to output either 64

× or 128× 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 5 V analog power supply and a 3.3 V digital power supply. The digital I/O pins

are compatible with 3.3 V logic families. The PCM4202 is available in a small SSOP-28 package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
