The PCM4201 is designed for digital audio applications that require a combination of high dynamic range, low distortion, and low power consumption. The primary applications for the PCM4201 include digital wireless microphones and battery-operated audio recording or processing equipment. The PCM4201 outputs 24-bit linear PCM audio data at sampling rates up to 108kHz. Three sampling modes allow the user to trade off power for performance, dependent upon the intended system requirements. An on-chip voltage reference reduces the number of external components needed for operation.

The PCM4201 includes dedicated control pins for configuration of all programmable functions. The device requires a +5.0V analog power supply, in addition to a digital supply operating from +1.8V to +3.3V. The PCM4201 is available in a small TSSOP-16 package.
