VREFOUT REFERENCE OUTPUT VOLTAGE
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:.
5V DIGITAL CHARACTERISTICS
(T
A
= -40 °C to +85 °C; VA+ = VD+ = 5 V ±10% VA-, DGND = 0 V) (See Notes 3, 4, and 13)
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).
