DESCRIPTION
The PCM1808-Q1 is high-performance, low-cost,
single-chip, stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1808-Q1
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-Q1 supports master and slave mode and
two data formats in serial audio interface.
The PCM1808-Q1 supports the power-down and
reset function by means of halting the system clock.
The PCM1808-Q1 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-
Q1 is fabricated using a highly advanced CMOS
process and is available in a small, 14-pin TSSOP
package.
