Description

The CS5509 is a single-supply, 16-bit, serial-output

CMOS A/D converter. The CS5509 uses charge-bal-

anced (delta-sigma) techniques to provide low-cost,

high-resolution measurements at output word rates up to

200 samples per second.

The on-chip digital filter offers superior line rejection at

50Hz and 60Hz when the device is operated from a

32.768 kHz clock (output word rate = 20 Sps).

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.
