The A132X linear Hall-effect sensors are optimized, sensitive, temperature-
stable linear Hall-effect sensors with greatly improved offset characteristics.
These ratiometric Hall-effect sensors provide a voltage output that is proportional
to the applied magnetic field. The linear family has a quiescent output voltage
that is 50% of the supply voltage and output sensitivity options of nominally
2.5mV/G, 3.125mV/G, and 5mV/G. The features of this linear family are ideal for
use in linear and rotary position sensing systems in harsh environments of
automotive and industrial applications over extended temperatures to –40 °C and
+150 °C.
Each BiCMOS monolithic circuit integrates a Hall element, improved
temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the
Hall element, a small-signal high-gain amplifier, and a rail-to-rail low-impedance
output stage.
A proprietary dynamic offset cancellation technique, with an internal high-
frequency clock reduces the residual offset voltage, which is normally caused by
device over molding, temperature dependencies, and thermal stress. The high
frequency clock allows for a greater sampling which produces higher accuracy
and faster signal processing capability, This technique produces devices that
have an extremely stable quiescent output voltage, are immune to mechanical
stress, and have precise recoverability after temperature cycling.
Having the
Hall element and an amplifier on a single chip minimizes many problems
normally associated with low-level analog signals.
Output precision is obtained by internal gain and offset trim adjustments
made at end-of-line during the manufacturing process.
The A132X family is provided in a 3-pin single inline package (Allegro UA
package) and a 3-pin surface mount package (Allegro LH package).
