CS5543

22-Bit, Multi-Channel ∆Σ ADC Chip Set

Features

Description

The CS5542 / CS5543 chip set is designed to be a com-

plete current measurement data acquisition system.

The CS5542 is a 22-Bit, 2-channel, 5th-order delta sig-

ma modulator. The CS5543 is a monolithic CMOS, 8-

channel digital FIR filter designed to be used with up to

four CS5542’s forming an 8-channel system. The com-

plete system is capable of cascading up to 1024

channels.

Delta-Sigma Architecture:

- 5th Order Modulator

- 22-Bit Resolution

dc Accuracy (f

= 250Hz):

- Integral Linearity: ±0.001 % F.S.

- Differential Linearity: ±0.5 LSBs

- RMS Noise: 1.1 pA_RMS

The system supports 22-bit measurement resolution

with output conversion rates up to 1 kHz per channel.

JTAG boundary-scan capability is available to facilitate

self-test at the system level.

Pin Selectable Input Range:

- ±400 nA to ±2.5 µA Full Scale

8-Channel Digital FIR Filter

Self-calibration of Offset and Gain

Low Power: 50 mW /ch for 8-ch system

Potential applications for the CS5542/CS5543 system

are environmental monitoring, process control systems,

color sensing, light measurement, chemical analyzers

and photo-diode transducer applications.
