Allegro MicroSystems A1373/A1374 High Precision Linear Hall Effect Sensors Datasheet
The A1373 and A1374 are high precision, temperature stable, linear devices with externally programmable features designed for automotive and industrial linear position-sensing applications. These sensors incorporate a chopper-stabilized amplifier, voltage regulator, programming logic, and an output amplifier on a single IC to provide extremely low offset and minimal temperature drift.
The devices feature field-programmable gain, quiescent offset voltage, sensitivity temperature coefficient, clamps, and polarity via the output pin. They are available in the KB package (3-pin SIP) with lead-free options featuring 100% matte tin plated leadframes.
