7 / 54 page CS5460A 7 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 (TA = -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).
