NOTES:
3. Input offset voltage measurements are performed by automatic test equipment approximately 0.5 seconds after applying power.
4. Long-term drift of input offset voltage refers to the average trend line of offset voltage versus time over extended periods after the
first 30 days of operation. Excluding the initial hour of operation, changes in VIO during the first 30 days are typically 2.5
