3 Description
The PCM1808 device is a high-performance, low-
cost, single-chip, stereo analog-to-digital converter
with single-ended analog voltage input. The
PCM1808 device uses a delta-sigma modulator with
64-times oversampling and includes a digital
decimation filter and high-pass filter that removes the
dc component of the input signal. For various
applications, the PCM1808 device supports master
and slave mode and two data formats in serial audio
interface.
The PCM1808 device supports the power-down and
reset functions by means of halting the system clock.
The PCM1808 device is suitable for wide variety of
cost-sensitive consumer applications requiring good
performance and operation with a 5-V analog supply
and 3.3-V digital supply. Fabrication of the PCM1808
device uses a highly advanced CMOS process. The
device is available in a small, 14-pin TSSOP
package.
