DESCRIPTION

The PCM1804-Q1 device is a high-performance,

single-chip stereo A/D converter with fully differential

analog voltage input which uses a precision delta-

sigma modulator and includes a linear-phase antialias

digital filter and high-pass filter (HPF) that removes

DC offset from the input signal. The PCM1804-Q1

device is suitable for a wide variety of mid- to high-

grade consumer and professional applications, where

excellent performance and 5-V analog supply and

3.3-V digital power-supply operation are required.

The PCM1804-Q1 device can achieve both PCM

audio and DSD format due to the precision delta-

sigma modulator. The PCM1804-Q1 device is

fabricated using an advanced CMOS process and is

available in a small 28-pin SSOP package.
