RATIOMETRIC, LINEAR HALL-EFFECT SENSORS

FOR HIGH-TEMPERATURE OPERATION

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.

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.
