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.
