    field, a voltage is induced across the conductor at right angles to the current flow. The strength of that induced voltage indicates the relative strength of the magnetic field. In Hall-effect sensors, current to be measured passes through a shunt path. This path is extremely low resistance, typically
  • First SOIC8-Packaged Hall-Effect Current Sensor With Integrated Current Path Introduced
    The newest current sensor family from Allegro MicroSystems, Inc., the ACS704, is the first SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater sensitivity and accuracy. The newest current sensor family from , the ACS704, is the first
