DESCRIPTION
The PCM1807 is high-performance, low-cost,
single-chip stereo analog-to-digital converter with
single-ended analog voltage input. The PCM1807
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
PCM1807 supports master and slave mode and two
data formats in serial audio interface.
The PCM1807 has many functions which are con-
trolled through SPI serial-control port: power down,
fade-in and fade-out, polarity control, etc.
The PCM1807 is suitable for wide variety of
cost-sensitive consumer applications where good per-
formance and operation with a 5-V analog supply and
3.3-V digital supply is required. The PCM1807 is
fabricated using a highly advanced CMOS process
and is available in a small, 14-pin TSSOP package.
