CDB5504 CS5504 CS5504 Evaluation Low-power, Board20-Bit 20-bit for CS5504 A/D Converter Converter A/D Converter Low Power, A/D Features Description 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 rejection at 50 Hz and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Sps). The CS5504 has on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors. Low power, high-resolution and small package size make the CS5504 an ideal solution for loop-powered transmitters, panel meters, weigh scales and batterypowered instruments.
