ADC14DC080 Dynamic Converter Electrical Characteristics
Unless otherwise specified, the following specifications apply: AGND = DRGND = 0V, VA = +3.0V, VDR = +2.5V, Internal VREF =
+1.2V, fCLK = 80 MHz, VCM = VCMO, CL = 5 pF/pin, . Typical values are for TA = 25°C. Boldface limits apply for TMIN ≤ TA ≤
TMAX. All other limits apply for TA = 25°C (Notes 8, 9)
