Figure 25. ADC Transfer Function
limits are within the safe operating area. Configure the
ADC for continuous conversions to allow continuous
measurement and testing against configured alarm
thresholds. Connect SAFE_ to OPSAFE_ to immediately
force the gate drive to GATEGND in the event of an
alarm-related condition (current or temperature).

Triggering DAC Calibration
Performing the autocalibration routines requires use of
the internal ADC, the internal ALU, and can also
increase the power dissipation of the part. Tables 28
and 29 detail which commands trigger autocalibration
and which commands do not.
