DESCRIPTION

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.
