PCM4220

SBAS407A – DECEMBER 2006 – REVISED MAY 2007

The PCM4220 is a high-performance, two-channel analog-to-digital (A/D) converter designed for use in

professional audio applications. Offering outstanding dynamic performance, the PCM4220 provides 24-bit linear

PCM output data, with support for output word length reduction to 20-, 18-, or 16-bits. The PCM4220 includes

three sampling modes, supporting output sampling rates from 8kHz to 216kHz. The PCM4220 is ideal for a

variety of digital audio recording and processing applications.

A linear phase digital decimation filtering engine supports Classic and Low Group Delay filter responses,

allowing optimization for either studio or live sound applications. In addition, digital high-pass filtering is provided

for DC offset removal. The The PCM4220 is configured using dedicated control pins for selection of sampling

modes, audio data formats and word length, decimation filter response, high-pass filter disable, and

reset/power-down functions.

While providing uncompromising performance, the PCM4220 addresses power concerns with just over 300mW

typical total power dissipation, making the device suitable for multi-channel audio systems. The PCM4220 is

typically powered from a +4.0V analog supply and a +3.3V digital supply. The digital I/O is logic-level compatible

with common digital signal processors, digital interface transmitters, and programmable logic devices. The

PCM4220 is available in a TQFP-48 package, which is RoHS-compliant.

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.
