General Description
The CDB5490U is an extensive tool designed to evaluate the
functionality and performance of Cirrus Logic’s CS5490 power
measurement device.
Multiple analog input connection options, configuration input fil-
ters, direct and isolated digital interfaces, multiple power supply
options, an onboard programmable microcontroller, visual LEDs
with an LCD panel make the board a flexible and powerful cus-
tomer development tool for various power measurement
applications.
The GUI software provides easy and complete access and con-
trol to the onboard CS5490 device. In addition, it includes the
function of raw ADC data collection with time domain, frequency
domain, and histogram analysis.
