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 controlled

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.
