The A1373 and A1374 high precision linear Hall effect sensors are ideal for use in automotive and industrial linear position-sensing applications that require increased reliability and accuracy over conventional contacting-potentiom- eter solutions.
The A1373 and A1374 are high precision, linear Hall effect sensors featuring a chopper-stabilized amplifier and voltage regulator on a single IC. These devices incorporate patented dynamic offset cancellation to provide extremely low offset and minimal temperature drift, making them ideal for automotive and industrial linear position-sensing applications such as throttle and pedal position sensors.

They are ideal for use in automotive and industrial linear position-sensing applications that require increased reliability and accuracy over conventional contacting-potentiometer solutions.
The devices can be programmed with a train of serial pulses via the output pin to set gain, quiescent output voltage, and temperature coefficient.
These devices are available in the KB package, which is a 3-pin SIP (single inline package).
