FSR
This value shows the deviation from the programmed B
∆TC
Included are the package-effect, the deviation from the adjusted temperature coefficient of the B
(resolution of the temperature coefficient and spread of the technologie) and the drift of the offset (over
temperature and lifetime). Not included is the hysteresis in the initial mode.
bigger amplitudes of signal lead to smaller values of B

normal distributed, nearly
independent to frequency and
without sampling noise or digital
noise effects. The typical value
represents the rms-value here
and corresponds therefore to 1σ
probability of normal distribution.
Consequently a 3σ value
corresponds to 0.3% probability
of appearance.
The typical value corresponds to
the rms-value at T
The max value corresponds to
the rms-values in the full
temperature range and includes
technological spreads.
