4.0 Application Hints
(Continued)
Temperature errors associated with non-ideality may be re-
duced in a specific temperature range of concern through
use of the offset registers (11h and 12h). Figure 14 shows
how the offset register may be used to compensate for the
non-ideality errors shown in Figure 13 For the case of
non-ideality=1.008, the offset register was set to 0.5C
resulting in the calculated residual error as shown in Figure
14 This offset has resulted in an error of less than 0.05C for
the temperatures measured in the critical range between 60
to 100C. This method yeilds a first order correction factor.
Please send an email to hardware.monitor.team

requesting further information on our recommended setting
of the offset register for different processor types.
