ACS720, Current Sensor

ACS720 High Accuracy, Dual Fault, Galvanically Isolated Current Sensor in SOIC16 Wide-Body Package .
The ACS720 is a high accuracy Hall-effect-based current sensor IC with multiple programmable fault levels intended for industrial and consumer applica.

Features

* Differential current sensing cancels common mode fields, simplifying PCB layout
* Two user-settable faults for fast short-circuit protection and slower overcurrent detection
* Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier

Applications

* Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients
* 5 V single supply operation with 0-3 V output swing
* Output voltage proportional to AC or DC current
* Factory-trimmed sensitivity and qu
