Description
The A1373 and A1374 high precision linear Hall effect
sensor ICs 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.
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 device can be set up in a magnetic
circuit and programmed with a train of serial pulses via the output
