CDB5504 Datasheet (Cirrus Logic) - 20-Bit A/D Converter

CDB5504, 20-Bit A/D Converter

The CS5504 is a 2-channel, fully differential 20-bit, serial-output CMOS A/D converter.

The CS5504 uses charge-balanced (delta-sigma) techniques to provide a low cost, high-resolution measurement at output word rates up to 200 samples per second.

The on-chip digital filter offers superior line rejec
