• Linear Position Sensing
• Current Sensing
DESCRIPTION
The 65025 Hall effect sensor detects the presence of a magnetic field and provides a switch output. It is
packaged in a hermetically sealed three pin ceramic package and can be used in many harsh environments. An
internal chopper stabilized amplifier eliminates input offset voltages normally associated with bipolar devices
resulting in improved operating point stability. The output transistor will be “latched ON” in the presence of a
sufficiently strong South pole magnetic field facing the marked side of the package. The output will be “latched
OFF” in the presence of a resetting North pole magnetic field.
