The CS5509 is a single-supply, 16-bit, serial-output analog-to-digital (A/D) converter for industrial applications. The CS5509 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 Hz).
The CS5509 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 CS5509 an ideal solution for loop-powered transmitters, panel meters, weigh scales and battery-powered instruments.
