Product Details

The ADM1270CP-EVALZ and ADM120RQ-EVALZ evaluation boards are used to demonstrate the functionality of the ADM1270 high voltage input protection device.

Simple device measurements, such as over voltage, undervoltage, and overcurrent protection can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistors.
