ACS711KLCTR-25AB-T

The ACS711KLCTR-25AB-T is a hall effect linear current sensor in 8 pin NSOIC package. This device provides economical and precise solutions for AC or DC current sensing in less than 100V isolation applications. It consists of a linear hall sensor circuit with copper conduction path located near surface of the die. Current flowing through this copper conduction path generates a magnetic field which is sensed by integrated hall IC and converted into a proportional voltage. Device accuracy is optimized through close proximity of magnetic signal to hall transducer. The ACS711 is optimized for low side current sensing applications. The terminals of conductive path are electrically isolated from sensor IC leads providing sufficient internal creepage and clearance dimensions for a low AC or DC working voltage applications.
