DESCRIPTION
The PCM1804 is a high-performance, single-chip
stereo A/D converter with fully differential analog
voltage input. The PCM1804 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 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 can achieve both PCM audio and
DSD format due to the precision delta-sigma
modulator. The PCM1804 is fabricated using an
advanced CMOS process and is available in a small
28-pin SSOP package.
