Description

The A1373 and A1374 high precision linear Hall effect sensors are sensitive, temperature stable, linear devices with externally programmable features. A1373 and A1374 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.

The design and manufacturing flexibility of the A1373 and A1374 complement the Allegro linear Hall effect family of devices by offering programmable gain, quiescent offset voltage for unipolar or bipolar operation, temperature coefficient, clamps, and polarity. The A1373 and A1374 can be set up in a magnetic circuit and programmed with a train of serial pulses via the output pin. Once the right combination of gain, quiescent output voltage, and temperature coefficient has been selected, the codes can be locked for one-time programming. In this manner, manufacturing tolerances can be reduced and the assembly process can be simplified.

A1373 and A1374 are available in the KB package, a 3-pin SIP (single inline package). The lead (Pb) free version has a 100% matte tin plated leadframe.
