The design is centered around a fully integrated, linear current sensor ACS712 from Allegro. The sensor (in SOIC8 package) consists of a precise, low-offset, linear Hall-effect sensor circuit with a ...

The ACS712 provides economical and precise solutions for ac or dc current sensing; the ACS713 provides dc current sensing only. Both devices consist of a precise, low-offset, linear Hall sensor ...

The ACS714 and ACS715 are similar to the ACS712 and ACS713 devices ... The devices consist of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface ...

Combining the Hall sensor with the conductor in a single package results in a current sensor that can be used to measure dc or ac currents. Allegro Microsystems’ ACS712, an example of this type ...
