VPP=|VNN|=90V. See Note 9.
Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 7: These voltage values are calculated and not 100% tested. The voltages are based on 100% tested

= 25 qC. See Application/Test Circuit on page 7. Unless otherwise noted, the supply voltage is
3
sense currents, the internal over-voltage and under-voltage resistors, and external “shift” resistors as
follows: RVPP1 = RVPP2 = 1.33M: RVNN1 = 1.21M: and RVNN2 = 3.57 M:. In addition, worse
case resistor tolerances (+/-1%) were used to calculate the minimum and maximum values. Please
refer to the Over-voltage and Under-voltage Protection section of the Applications Information on how
to set the operating voltage supply range.
