DESCRIPTION
The PCM1808 is high-performance, low-cost,
single-chip, stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1808
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 supports master and slave mode and two
data formats in serial audio interface.
The PCM1808 supports the power-down and reset
function by means of halting the system clock.
The PCM1808 is suitable for wide variety of
cost-sensitive consumer applications where good
performance and operation with a 5-V analog supply
and 3.3-V digital supply is required. The PCM1808 is
fabricated using a highly advanced CMOS process
and is available in a small, 14-pin TSSOP package.
