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.
