General Description
●The MAX4080/MAX4081 are high-side, current-sense amplifiers 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. The MAX4080 is designed for unidirectional current-sense applications and the MAX4081 allows bidirectional current sensing.
