TI PCM1804DBR

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