Electrical Characteristics (continued)

(VAVDD1 = VAVDD2 = VDVDD = VDVDDO = 5V, VAGND1 = VDGND = VDGNDO = VAGND2 = VAGND3 = 0V, 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.)
