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.
