MAX4080SAUA+

The MAX4080SAUA+ is a 76V, high side, current sense amplifier with voltage output in 8 pin µMAX package. The device 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+). High side current monitoring does not interfere with the ground path of the load being measured, this makes the device particularly useful in wide range of high voltage systems. Device offer a high level of integration resulting in a simple, accurate and compact current sense solution makes device ideal for telecom, automotive, backplane and other systems where high voltage current monitoring is critical.
