t
Occurrence of Initial Calibration Delay Time
d,input
If there is no input signal (standstill), a new initial calibration is triggered each 0.7 s. This
t
calibration has a duration
of max. 300 µs. No input signal change is detected during
d,input
that initial calibration time.
t
In normal operation (signal startup) the probability of
to come into effect is:
d,input
t
/ time frame for new calibration 300 µs/700 ms = 0.05%.
d,input
t
After IC resets (e.g. after a significant undervoltage)
will always come into effect.

Magnetic Input Signal Extremely Close to a Switching Threshold of PGA at Signal
Startup
After signal startup generally all PGA switching into the appropriate gain state happens
within less than one signal period. This is included in the calculation for n
. For the
DZ-Start
very rare case that the signal amplitude is extremely close to a PGA switching threshold
and the full range of following speed ADC respectively, a slight change of the signal
amplitude can cause one further PGA switching. It can be caused by non-perfect
magnetic signal (e.g. amplitude modulation due to tolerances of pole-wheel, tooth wheel
or air gap variation). This additional PGA switching can result in a further delay of the
output signal (n
) up to three magnetic edges leading to a worst case of n
= 9.
DZ-Start
DZ-Start
Due to the low probability of this case it is not defined as max. value in the data sheet.
