3 Description

The PCM1802 is a high-performance, low-cost,

single-chip stereo analog-to-digital converter with

single-ended analog voltage input. The PCM1802

uses a delta-sigma modulator with 64-times or

128

‑times

oversampling,

and

includes

a

digital

decimation filter and high-pass filter (HPF), which

removes the DC component of the input signal. For

various applications, the PCM1802 supports master

and slave modes and four data formats in serial

interface. The PCM1802 is suitable for a wide variety

of cost-sensitive consumer applications where good

performance, 5-V analog supply, and 3.3-V digital

supply operation is required. The PCM1802 is

fabricated using a highly advanced CMOS process

and is available in the DB 20-pin SSOP package.
