Product Summary
The MAX4080TAUA+T is a 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. The MAX4080TAUA+T is designed for unidirectional current-sense applications. For maximum versatility, the 76V input voltage range applies independently to both supply voltage (VCC) and common-mode input voltage (VRS+). The applications of the MAX4080TAUA+T include Automotive (12V, 24V, or 42V Batteries), 48V Telecom and Backplane Current Measurement, Bidirectional Motor Control, Power-Management Systems, Avalanche Photodiode and PIN-Diode Current, Monitoring, General System/Board-Level Current Sensing, Precision High-Voltage Current Sources.
