ACS724LLCTR-05AB-T [Allegro]

The ACS724 current sensor IC features a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. The current is sensed differentially in order to reject common-mode fields, improving accuracy in magnetically noisy environments. The device provides galvanic isolation and is available in a small-footprint SOIC8 package. It includes patented integrated digital temperature compensation for near closed-loop accuracy over temperature, a filter pin for bandwidth limiting, and chopper stabilization for stable quiescent output voltage.
