RATIOMETRIC, LINEAR HALL-EFFECT SENSORS
FOR HIGH-TEMPERATURE OPERATION
The A3517xUA and A3518xUA are sensitive, temperature-stable linear
Hall-effect sensors with greatly improved offset characteristics. Ratiometric,
linear Hall-effect sensors provide a voltage output that is proportional to the
applied magnetic field and have a quiescent output voltage that is approxi-
mately 50% of the supply voltage. These magnetic sensors are ideal for use in
linear and rotary position sensing systems in the harsh environments of
automotive and industrial applications over extended temperatures to -40°C
and +150°C. The A3517xUA features an output sensitivity of 5 mV/G while
the A3518xUA has an output sensitivity of 2.5 mV/G. See the Magnetic

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.

Pinning is shown viewed from branded side.
A proprietary dynamic offset cancelation technique, with an internal high-
frequency clock, reduces the residual offset voltage, which is normally caused
by device overmolding, temperature dependancies, and thermal stress. This
technique produces devices that have an extremely stable quiescent output
voltage, are immune to mechanical stress, and have precise recoverability after
temperature cycling. Many problems normally associated with low-level
analog signals are minimized by having the Hall element and amplifier in a
single chip. Output precision is obtained by internal gain and offset trim
adjustments during the manufacturing process.

NOTE 2 Negative current is defined as coming out of (sourcing) the output.
* This test requires positive and negative fields sufficient to swing the output driver between fully OFF and saturated (ON),
respectively. It is NOT intended to indicate a range of linear operation.
