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.
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.
Potential applications for the CS5542/CS5543 system
are environmental monitoring, process control systems,
color sensing, light measurement, chemical analyzers
and photo-diode transducer applications.
