ADC14C105 Converter Electrical Characteristics
This product is currently under development. As such, the parameters specified are DESIGN TARGETS. The specifica-
tions cannot be guaranteed until device characterization has taken place.
Unless otherwise specified, the following specifications apply: AGND = DRGND = 0V, VA = +3.3V, VDR = +2.5V, Internal VREF =
+1.2V, fCLK = 105 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)
