The CS5509 is a single-supply, 16-bit, serial-outputCMOS A/D converter. The CS5509 uses charge-balanced(delta-sigma) techniques to provide low-cost,high-resolution measurements at output word rates up to200 samples per second.The on-chip digital filter offers superior line rejection at50Hz and 60Hz when the device is operated from a32.768 kHz clock (output word rate = 20 Sps).The CS5509 has on-chip self-calibration circuitry whichcan be initiated at any time or temperature to ensureminimum offset and full-scale errors.Low power, high resolution, and small package sizemake the CS5509 an ideal solution for loop-poweredtransmitters, panel meters, weigh scales, and batterypowered instruments.
