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.
