SENSOR LOCATION
APPLICATIONS INFORMATION
Calibrated linear Hall devices, which can be used to
determine the actual flux density presented to the sensor in a
particular application, are available.
For safe, reliable operation, the output should not be
pulled above the supply voltage or pulled below the device
ground.
For optimum performance, a 100 pF capacitor between
the output and ground should be added.
The nominal sensitivity is factory set to compensate for
the temperature coefficient of samarium-cobalt magnets
(-0.02%/
°C).
The ratiometric feature is especially valuable when these
devices are used with an analog-to-digital converter. A/D
converters typically derive their LSB step size by ratioing off a
reference voltage line. If the reference voltage varies, the LSB
will vary proportionally. This is a major error source in many
sensing systems. The A3507/08– can eliminate this source of
error by their ratiometric operation. Because their gain and
offsets are proportional to the supply voltage, if they are
powered from the A/D reference voltage, the sensor output
voltage will track changes in the LSB value.
Hall-effect applications information is available in the
application note “Linear Hall-Effect Sensors” (AN 27702),
which can be found in the latest issue of Allegro Electronic
Data Book, AMS-702, or at
