EVALUATION AND DESIGN SUPPORT
Circuit Evaluation Boards
Design and Integration Files
Rev.A
Circuits from the Lab™ circuits from Analog Devices have been designed and built by Analog Devices
engineers. Standard engineering practices have been employed in the design and construction of
each circuit, and their function and performance have been tested and verified in a lab environment at
room temperature. However, you are solely responsible for testing the circuit and determining its
suitability and applicability for your use and application. Accordingly, in no event shall Analog Devices
be liable for direct, indirect, special, incidental, consequential or punitive damages due to any cause
whatsoever connected to the use of any Circuits from the Lab circuits. (Continued on last page)

CIRCUIT FUNCTION AND BENEFITS
The circuit shown in Figure 1 monitors current in individual
channels of −48 V to better than 1% accuracy. The load current
passes through a shunt resistor, which is external to the circuit.
The shunt resistor value is chosen so that the shunt voltage is
approximately 50 mV at maximum load current.

... Care should be taken in considering the isolation gap between the primary and secondary sides of the ADuM5402. The EVAL-CN0188-SDPZ board maximizes this distance by pulling back any polygons or components on the top layer and aligning them with the pins on the ADuM5402. Power supply lines should have as large a trace width as possible ...
