In addition to defining the magnetic operate point, these two digits are used to define the
direction of sensitivity and optional low voltage operation. The GMR Switch can be
ordered in Standard Axis or Cross Axis directions of sensitivity; for definitions please see
NVE AD Series Sensitivity Direction and Pin Configuration later in this section.
NVE also makes a GMR Switch with the on-chip voltage regulator bypassed. This limits
the voltage range of the part, but allows it to operate at voltages as low as 3.0V.
The following table defines the second and third digits in the NVE AD part number:
NVE AD x xx-xx
Note: For parts that operate at 10 Gauss, see the following section describing the NVE
ADH Series sensors.
NVE AD Series Sensitivity Direction and Pin Configuration
Pin configuration is for the NVE AD Series GMR Switches is given in the following
diagrams. In addition, most GMR Switch parts are available with a choice of two
directions of sensitivity. “Standard” direction of sensitivity is defined as the direction
parallel to the edge of the package containing the pins. “Cross-Axis” direction of
