Ratiometric Linear Hall Effect Sensor

for High-Temperature Operation

Characteristic Deﬁnitions

Quiescent Voltage Output. In the quiescent state (no

Ratiometric. The A132X family features a ratiometric output.

magnetic ﬁeld), the output equals one half of the supply voltage

over the operating voltage range and the operating temperature

range. Due to internal component tolerances and thermal con-

siderations, there is a tolerance on the quiescent voltage output

both as a function of supply voltage and as a function of ambient

temperature. For purposes of speciﬁcation, the quiescent voltage

output as a function of temperature is deﬁned in terms of mag-

netic ﬂux density, B, as:

The quiescent voltage output and sensitivity are proportional to

the supply voltage (ratiometric).

The percent ratiometric change in the quiescent voltage output is

deﬁned as:

V_out(q)(V

V_out(q)(5V)

ΔV_out(q)(ΔV)

V_CC5 V

and the percent ratiometric change in sensitivity is

deﬁned as:

This calculation yields the device’s equivalent accuracy,

over the operating temperature range, in gauss (G).

Linearity and Symmetry. The on-chip output stage

Sensitivity. The presence of a south-pole magnetic ﬁeld per-

pendicular to the package face (the branded surface) increases

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:

is designed to provide a linear output with a supply voltage of

5 V. Although application of very high magnetic ﬁelds will not

damage these devices, it will force the output into a non-linear

region. Linearity in percent is measured and deﬁned as:

V_out(+B)V_out(q)
