Description:
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 1.5 kΩ nominal resistance
and output of each half-bridge is ratiometric with the power supply voltage. The part features NVE’s
PLLP6 housing, which is a 3.0 mm x 3.0 mm x 0.9 mm thick surface mount package.
Operation:
The sensor elements contain two magnetic layers: a pinned, or fixed-direction layer, and a movable or
free layer. The diagram below illustrates the configuration with arrows representing the two layers:
