Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The PCM1804 is a high-performance single chip stereo A/D converter with full differential analog voltage input.

The PCM1804 uses a precision delta-sigma modulator and includes a linear phase antialias digital filter and HPF (low-cut filter) that removes dc offset of 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 precision delta-sigma modulator. The PCM1804 is fabricated on an advanced CMOS process and is available in small 28-pin SSOP package.
