3517 AND 3518

RATIOMETRIC,

LINEAR HALL-EFFECT SENSORS

FOR HIGH-TEMP. OPERATION

CHARACTERISTICS DEFINITIONS

Quiescent Voltage Output. In the quiescent state (no

magnetic field), the output is ideally equal to one-half of

the supply voltage over the operating voltage and tem-

perature range (V_OQ≈ V_CC/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

Ratiometry. The A3517xUA and A3518xUA 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

V_OQ(VCC)/ V_OQ(5V)

∆V_OQ(∆V)

x 100%

V_CC/ 5 V

V_OQ(TA)– V_OQ(25°C)

∆V_OQ(∆T)

Sens_(25°C)

and the per cent ratiometric change in sensitivity is defined

This calculation yields the device’s equivalent

accuracy, over the operating temperature range, in gauss.

Sens_(VCC)/ Sens_(5V)

∆Sens_(∆V)

x 100%

V_CC/ 5 V

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

Linearity and Symmetry. The on-chip output stage is

designed to provide a linear output to within 500 mV of

either rail with a supply voltage of 5 V. This is equivalent

to approximately ±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

V_O(500G)– V_O(-500G)
