CS5509

Single-supply, 16-bit A/D Converter

Features

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.

z Delta-sigma A/D Converter

16-bit, No Missing Codes

Linearity Error: ±0.0015%FS

z Differential Input

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).

Pin-selectable Unipolar/Bipolar Ranges

Common Mode Rejection

105 dB @ dc

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.

120 dB @ 50, 60 Hz

z Either 5V or 3.3V Digital Interface

z On-chip Self-calibration Circuitry

z Output Update Rates up to 200/second

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.
