Allegro - A1342 Programmable Linear Hall IC

The A1342 device is a high-precision, programmable Hall-effect
linear sensor integrated circuit (IC) with an open-drain output,
for both automotive and nonautomotive applications. The
signal path of the A1342 provides flexibility through external
programming that allows the generation of an accurate, and
customized, output from an input magnetic signal.

The A1342 is an especially configurable and robust solution
for the most demanding linear field sensor applications. The
BiCMOS, monolithic IC incorporates a Hall sensing element,
precision temperature-compensating circuitry to reduce the
intrinsic sensitivity and offset drift of the Hall element, a
small-signal high-gain amplifier, proprietary dynamic offset
cancellation circuits, advanced output linearization circuitry,
and advanced diagnostics. The A1342 provides an unmatched
level of customer-programmable options.
