Product Summary

The MAX4080SASA is a kind of high-side, current-sense amplifier with an input voltage range that extends from 4.5V to 76V making them ideal for telecom, automotive, backplane, and other systems where high-voltage current monitoring is critical. It is designed for unidirectional current-sense applications. The device offers a high level of integration, resulting in a simple, accurate, and compact current-sense solution.
