Note 1: Parameter tested at AV DD1 = AV DD2 = DV DD = DV DDO = 5V.
Note 2: See definitions in the Parameter Definitions section at the end of the data sheet.
Note 3: Guaranteed by correlation with single-ended measurements.
Note 4: Not production tested. Guaranteed by design.
Note 5: To ensure external reference operation, V
REFCAP must exceed (AV DD1 - 0.1V). To ensure internal reference operation, V REFCAP
must be below (AV DD1 - 0.4V). Bypassing REFCAP with a 0.1µF or larger capacitor to AGND1 sets VREFCAP ≈ 4.096V. The tran-
sition point between internal reference mode and external reference mode lies between the REFCAP buffer disable threshold
minimum and maximum values (Figures 17 and 18).
Note 6: The SCLK duty cycle can vary between 40% and 60%, as long as the t CL and t CH timing requirements are met.
