Texas Instruments PCM1804DB

Description
The PCM1804 is a high-performance, single-chip stereo A/D converter with fully differential analog voltage input. It utilizes a precision delta-sigma modulator and incorporates a linear phase antialias digital filter and high-pass filter (HPF) to remove DC offset from the input signal. The PCM1804 is suitable for various mid- to high-grade consumer and professional applications requiring excellent performance and 5V analog supply and 3.3V digital power supply operation. It can achieve both PCM audio and DSD format due to its precision delta-sigma modulator. The PCM1804 is fabricated using an advanced CMOS process and is available in a small 28-pin SSOP package.
