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.
