DESCRIPTION

The PCM1803 is high-performance, low-cost,

single-chip stereo analog-to-digital converter with

single-ended analog voltage input. The PCM1803

uses a delta-sigma modulator with 64-, 128-times

oversampling, and includes a digital decimation filter

and high-pass filter which removes the DC

component of the input signal. For various

applications, the PCM1803 supports master and

slave modes and four data formats in serial interface. The PCM1803 is suitable for a wide variety of

cost-sensitive consumer applications where good

performance and operation from a 5-V analog supply

and 3.3-V digital supply are required. The PCM1803

is fabricated using a highly advanced CMOS process

and is available in a small 20-pin SSOP package.
