8 / 42 page  AC Electrical Characteristics The following specifications apply for (V + =V A+=VD+ = +5V, VREF+ = +4.096V, and fully-differential input with fixed 2.048V common-mode voltage) or (V + =V A+=VD+ = +3.3V, VREF+ = +2.5V and fully-differential input with fixed 1.250V common- mode voltage), V REF− = 0V, 12-bit + sign conversion mode, source impedance for analog inputs, VREF− and VREF+ ≤ 25Ω,f CK =f SK = 5 MHz, and 10 (tCK) acquisition time unless otherwise specified. Boldface limits apply for TA =TJ =TMIN to TMAX; all other limits T A =TJ = 25˚C.
