Texas Instruments PCM1804 Stereo Analog-to-Digital Converter 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 5V analog supply and 3.3V digital power-supply operation are required. The PCM1804 can achieve both PCM audio and DSD format due to the precision delta-sigma modulator. The Texas Instruments PCM1804 is fabricated using an advanced CMOS process and is available in a small 28-pin SSOP package.
