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.
