RATIOMETRIC,

LINEAR HALL-EFFECT SENSORS

FOR HIGH-TEMP. OPERATION

APPLICATIONS INFORMATION

TYPICAL CURRENT-SENSING APPLICATION

Calibrated linear Hall devices, which can be used to

determine the actual flux density presented to the sensor in a

particular application, are available.

B ≈ N x 6.9 G/A

For safe, reliable operation, the output should not be pulled

above the supply voltage or pulled below the device ground.

For optimum performance, a 0.1 µF capacitor between the

supply and ground, and a 100 pF capacitor between the output

and ground, should be added.

Dwg. AH-005A

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 A3517xUA and A3518xUA 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.

These devices can withstand infrequent temperature

excursions, beyond the Absolute Maximum Ratings, to

T_A= 170°C provided the junction temperature, T_J, does not

exceed 200°C.

Extensive applications information on Hall-effect sensors

and magnets is also available in the “Hall-Effect IC Applications

Guide”, which can be found in the latest issue of the Allegro
