The PCM4222 is a high-performance, two-channel analog-to-digital (A/D) converter designed for use in professional audio applications. Offering outstanding dynamic performance, the PCM4222 supports 24-bit linear PCM, 1-bit Direct Stream Digital (DSD), and 6-bit modulator data outputs. The supported output formats make the PCM4222 ideal for digital audio recording and processing applications. The multi-bit modulator output adds versatility, allowing customers to design their own digital decimation filter and processing hardware. The on-chip, linear phase decimation filtering engine supports Classic and Low Group Delay filter responses, allowing optimization for either studio or live sound applications.

The PCM4222 includes three PCM sampling modes, supporting output sampling rates from 8kHz to 216kHz. The DSD output supports either 64x or 128x oversampled bit rates. The PCM4222 is configured using dedicated control pins for selection of output modes, PCM audio data formats and word length, decimation filter response, high-pass filter disable, and reset/power-down functions.

While providing uncompromising performance, the PCM4222 addresses power concerns with just over 300mW typical total power dissipation, making the device suitable for multi-channel audio systems. The PCM4222 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 PCM4222 is available in a TQFP-48 package, which is RoHS-compliant.
