The AAV001-11 and AAV002-11 are arrays of four GMR resistors, rotated at 90
degree intervals in the package. The AAV001-11 features independent resistors that can be wired
together to form two half bridges, or used as independent resistors. The AAV002-11 has the bridge
connections made internally to the package. For either part, the output can be configured to represent
the sine and cosine function of the magnetic field being applied to the sensor. Each resistor is 1.2KOhms
nominal resistance, and output of each half bridge is ratiometric with the power supply voltage. The part
features NVE鈥檚 PLLP6 housing, which is a 3.0mm X 3.0mm X 0.9mm thick surface mount package.
Operation
鈥?/div>
The end user must apply a magnetic field planar with the IC package.
As this magnetic
field varies, the resistance values of the individual resistors change and output is provided by the half
bridges. An example output signal is shown in the diagram below:
