defined as: the time it takes for the output voltage to settle within
±1% of its steady state value, after initially passing through its
steady state voltage, as shown in the following chart.

Average Quiescent Voltage Output Step Size
escent voltage output step size for a single device is determined
using the following calculation:
where:
Quiescent Voltage Output Programming Resolution
programming resolution for any device is half of its programming
step size. Therefore, the typical programming resolution will be:

Sensitivity
pendicular to the branded surface of the package face, increases
the output voltage from its quiescent value toward the supply
voltage rail. The amount of the output voltage increase is propor-
tional to the magnitude of the magnetic field applied. Conversely,
the application of a north polarity field decreases the output
voltage from its quiescent value. This proportionality is specified
as the magnetic sensitivity, Sens (mV/G), of the device, and it is
defined for bipolar devices as:
and for unipolar devices as:
where BPOS and BNEG are two magnetic fields with opposite
polarities.
