Hall Effect Sensor Bipolar/Unipolar 5V 3Pin SIP Bulk
Description
The A1373 and A1374 high precision linear Hall effect sensors are sensitive, temperature stable, linear devices with externally programmable features. This device family incorporates a chopper-stabilized amplifier, voltage regulator, programming logic, and an output amplifier on a single IC. The patented dynamic offset cancellation used with a chopper-stabilization technique provides extremely low offset and minimal temperature drift. A high frequency clock is used for chopping, to ensure high frequency signal processing capability. The A1373 and A1374 are ideal for use in automotive and industrial linear position-sensing applications that require increased reliability and accuracy over conventional contacting-potentiometer solutions. Key applications include: throttle position sensors, pedal position sensors, and suspension height sensors.
