Description: Low-Cost / Precision / High-Side Current-Sense Amplifier

Features

* o Low-Cost, High-Side Current-Sense Amplifier o ±0.5% Typical Full-Scale Accuracy Over Temperature o 3V to 32V Supply Operation o 0V to 32V Input Range
* Independent of Supply Voltage o 800kHz Bandwidth [VSENSE = 100mV (1C)] 200kHz Bandwidth [VSENSE = 6.25mV (C/16)] o Available in Space-Saving

Applications

* The 0V to 32V input common-mode range is independent of the supply voltage, which ensures that current-sense feedback remains viable, even when connected to a battery in deep discharge. To provide a high level of flexibility, the MAX4172 functions with an external sense resistor to set the range of
