Note 1: Parameter tested at VAVDD1 = VAVDD2 = VDVDD = VDVDDO = 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, VREFCAP must exceed (VAVDD1 - 0.1V). To ensure internal reference operation, VREFCAP
must be below (VAVDD1 - 0.4V). Bypassing REFCAP with a 0.1F 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 tCL and tCH timing requirements are met.
