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
(±12V), CDOUT = 50pF, CSSTRB = 50pF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
