General Description
The CDB5484U is an extensive tool designed to evaluate the
functionality and performance of Cirrus Logic’s CS5484 pow-
er/energy measurement device.
Multiple analog input connection options, configuration input fil-
ters, direct and isolated digital interfaces, multiple power supply
options, an onboard programmable microcontroller, and visual
LEDs with an LCD panel make the board a flexible and powerful
customer development tool for various power/energy measure-
ment applications.
The GUI software provides easy and complete access and con-
trol to the onboard CS5484 device. It also includes the function
of raw ADC data collection with time domain, frequency domain,
and histogram analysis.
Schematics in the PADS™ PowerLogic™ format are available
on request.
