Note 5: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 6: These supply voltages are calculated using the IVPPSENSE and IVNNSENSE values shown in the Electrical
Characteristics table. They are shown for example only and are based on a +/-45V typical supply voltage.
The voltage values shown are calculated using RVPP and RVNN values without any tolerance variation.
Tripath recommends 1% tolerance (or better) sense resistors for all applications. Please refer to the
Application Information section for a more detailed description of how to calculate the over and under
voltage trip voltages for a given resistor value.
