Electrical Characteristics (continued)

Unless otherwise noted, these specifications apply for VDD=4.75V to 5.25V, REF=VDD, TA=25°C. Boldface limits are over

the temperature range of

−30°C ≤ TA ≤ 85°C unless otherwise noted. DAC input code range 12 to 1012. DAC output

CL = 200 pF unless otherwise noted.
