A1373 and A1374 are high precision linear Hall effect sensors with external programmable features, which are produced by Allegro MicroSystems, Inc. It has extremely low offset and minimal temperature drift. It can be used 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, temperature stable, linear devices with externally programmable features designed for automotive and industrial linear position-sensing applications. They incorporate a chopper-stabilized amplifier and voltage regulator on a single IC to provide extremely low offset and minimal temperature drift.
These sensors offer selectable coarse and fine gain, quiescent output voltage, sensitivity temperature coefficient, output clamp voltage level, and polarity. The devices are available in the KB package (3-pin SIP) and can be programmed via the output pin with a train of serial pulses to lock specific combinations of gain, offset, and temperature coefficient.
| Supply Voltage (Vcc) | 4.5 V to 5.5 V |
|---|---|
| Chopping Frequency | 200 kHz |
| Output Capacitance | 10 nF |
Key applications include throttle position sensors, pedal position sensors, and suspension height sensors.
The device can be set up in a magnetic circuit and programmed with a train of serial pulses via the output pin.
