Part Number Specifications and Availability
ACS711 Product Overview
The Allegro ACS711 provides economical and precise solutions for AC or DC current sensing in 100+ V audio, communications systems, clean energy, personal mobility and white goods. The device package allows for easy implementation by the customer.
The device consists of a 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.
