Serial 16-Bit ADCs

ELECTRICAL CHARACTERISTICS (continued)

(AVDD1 = AVDD2 = DVDD = DVDDO = 5V, AGND1 = DGND = DGNDO = AGND2 = AGND3 = 0, fCLK = 3.5MHz (50% duty cycle),

external clock mode, VREF = 4.096V (external reference operation), REFCAP = AVDD1, maximum single-ended bipolar input range

(±3 x VREF), CDOUT = 50pF, CSSTRB = 50pF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: Parameter tested at AVDD1 = AVDD2 = DVDD = DVDDO = 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 (AVDD1 - 0.1V). To ensure internal reference operation, VREFCAP

must be below (AVDD1 - 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 tCL and tCH timing requirements are met.
