The A3507– and A3508– are 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 two devices 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, im-
proved 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.
The first character of the part number suffix determines the device
operating temperature range: suffix ‘S–’ is for -20°C to +85°C, suffix
‘E–’ is for -40°C to +85°C, and suffix ‘L–’ is for -40°C to +150°C.
These devices are supplied in a 3-pin ultra-mini-SIP ‘–UA’ package.

LINEAR HALL-EFFECT SENSORS
FOR HIGH-TEMP. OPERATION
CHARACTERISTICS DEFINITIONS
Quiescent Voltage Output. In the quiescent state (no mag-
netic field), the output is ideally equal to one-half of the supply
voltage over the operating voltage and temperature range (VOQ
VCC/2). Due to internal component tolerances and thermal
considerations, there is a tolerance on the quiescent voltage
output and on the quiescent voltage output as a function of
supply voltage and ambient temperature. For purposes of
specification, the quiescent voltage output as a function of
temperature is defined as
VOQ(T)
=
VOQ(TA) – VOQ(25°C)
Sens(25°C)
(1)
This calculation yields the device’s equivalent accuracy,
over the operating temperature range, in gauss.
Sensitivity. The presence of a south-pole magnetic field
perpendicular to the package face (the branded surface) will
increase the output voltage from its quiescent value toward the
supply voltage rail by an amount proportional to the magnetic
field applied. Conversely, the application of a north pole will
decrease the output voltage from its quiescent value. This
proportionality is specified as the sensitivity of the device and
is defined as
Sens = VO(500G) – VO(-500G)
1000 G
(2)
The stability of sensitivity as a function of temperature is
defined as
Sens(T) =
Sens(TA) – Sens(25°C)
Sens(25°C)
x 100%
(3)
Ratiometry. The A3507– and A3508– feature a ratiometric
output. The quiescent voltage output and sensitivity are
proportional to the supply voltage (ratiometric).
The per cent ratiometric change in the quiescent voltage
output is defined as
VOQ(V)
=
VOQ(VCC) / VOQ(5V)
VCC / 5 V
x 100%
(4)
and the per cent ratiometric change in sensitivity is defined as
Sens(V)
=
Sens(VCC)
VCC /
/ Sens(5V)
5V
x 100%
(5)
Linearity and Symmetry. The on-chip output stage is de-
signed to provide a linear output to within 500 mV of either rail
with a supply voltage of 5 V. This is equivalent to approxi-
mately ±800 gauss of ambient field. Although application of
stronger magnetic fields will not damage these devices, it will
force the output into a non-linear region. Linearity in per cent
is measured and defined as
Lin+ = VO(500G) – VOQ x 100%
2 (VO(250G) – VOQ)
(6)
Lin– = VO(-500G) – VOQ x 100%
2 (VO(-250G) – VOQ)
and output symmetry as
(7)
Sym = VO(500G) – VOQ x 100%
VOQ – VO(-500G)
