Electrical Characteristics (Continued) Values shown in this table are design targets and are subject to change before product release. The following specifica- tions apply for V A = +2.7V to +5.5V, VREFIN =VA,CL = 200 pF to GND, fSCLK = 30 MHz, input code range 48 to 4047. Bold- face limits apply for T MIN ≤ T A ≤ T MAX and all other limits are at TA = 25˚C, unless otherwise specified.
