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

= -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).
