DESCRIPTION
●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.
