This PCM1804 is a high-performance single-chip stereo A/D converter with fully differentiated analog input voltage. It uses a precision PCM1804Δ-Σ modulator and includes a linear phase-digital anti-aliasing filter and a high-pass filter (HPF) to eliminate DC offset input signals. This PCM1804 is suitable for a wide range of mid-to-high-end consumer and professional applications, where excellent performance and 5V analog power supply and 3.3V digital power operation are essential. Both PCM and DSD audio formats can be PCM1804 thanks to the precision of Δ-Σ modulators. It is a fabricated PCM1804 using advanced CMOS technology and a compact 28-pin SSOP package.
