3506, 3507, AND 3508
RATIOMETRIC, LINEAR HALL-EFFECT SENSORS
FOR HIGH-TEMPERATURE OPERATION
The A3506–, A3507–, and A3508– comprise a family of sensitive,
temperature-stable linear Hall-effect sensors. 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 three devices in this series are
similar except for temperature stability over the operating temperature
range. See the Magnetic Characteristics table for complete, individual
device parametrics.
Each monolithic circuit integrates a quadratic 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. 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 mini-SIP “U” package or a
3-pin ultra-mini-SIP “UA” package.
