Notes: 12. The voltage at VREFOUT is measured across the temperature range. From these measurements the
following formula is used to calculate the VREFOUT Temperature Coefficient:.
(VREFOUTMAX - VREFOUTMIN)

13. Note that the 5 V characteristics are guaranteed by characterization. Only the more rigorous 3.3 V
digital characteristics are actually verified during production test.
14. Applies to all INPUT pins except XIN pin (leakage current < 50 µA) and MODE pin (leakage current <
25 µA).
