Application Notes
Current Measurement
Basic concepts
GMR Magnetic Field Sensors can effectively sense the magnetic field generated by a current. The
figure below illustrates the sensor package orientation for detecting the field from a current-carrying
wire. This application allows for current measurement without breaking or interfering with the circuit
of interest. The wire can be located above or below the chip, as long as it is oriented perpendicular to
the sensitive axis.
