Electrical Characteristics (continued)

Values shown in this table are design targets and are subject to change before product release.

The following specifications apply for VA = +2.7V to +5.5V, RL = 2kΩ to GND, CL = 200 pF to GND, fSCLK = 30 MHz, input

code range 4 to 251. Boldface limits apply for TMIN ≤ TA ≤ TMAX: all other limits TA = 25°C, unless otherwise specified.
