RATIOMETRIC, LINEAR HALL-EFFECT SENSORS
FOR HIGH-TEMPERATURE OPERATION
V
CC
The A3515– and A3516– 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 approximately 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
A3515– features an output sensitivity of 5 mV/G, while the A3516– has an
output sensitivity of 2.5 mV/G. See the Magnetic Characteristics table for
complete, individual device parametrics.

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 recover-
ability 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.
These devices are supplied in a 3-pin ultra-mini-SIP ‘UA’ package.

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), respec-
tively. It is NOT intended to indicate a range of linear operation.
