Application Notes
The figure below shows another configuration where a current trace on a PCB is under the board-
mounted sensor.

An Excel spreadsheet is available on NVE’s web site which helps calculate the magnetic field at the
sensor from a current carrying trace on the board as shown in the diagram above.
Principles of Operation
The magnetic field created by the current surrounds the conductor radially. As the magnetic field
affects the GMR material in the sensor, a differential output is produced at the out pins of the sensor.
The magnetic field strength is directly proportional to the current flowing through the conductor. As
the current increases, the surrounding magnetic field will also increase, thus increasing the output from
the sensor. Similarly, as the current decreases, the magnetic field and sensor output decrease.
Since the current is not measured directly, the sensor output must be correlated to the current. The
following data and graphs are based upon analysis of NVE’s evaluation board contained in our current
sensor evaluation kit, part number AG003-01. The PCB contains four traces of three different widths:
90 mils, 60 mils, and 10 mils.
