Part Number: ADC14C105
I didn't found the input impedance for this ADC in the datasheet. For some calculation and matching with a PGA870 I'm intessted in this data.
Do you can provide me this data.
I did an initial look but haven't found any s-parameter or other information regarding the input impedance of this device.
The analog inputs are primarily capacitive. The capacitance value of each input (Cin) is listed in the specification table on page 7 of the datasheet. The values are 8.5pF when CLK is low and 3.5 pF when CLK is high.
I'll check some more and post again if I find any other information.
In reply to Jim Brinkhurst84999:
thank you for your feedback.
Yes this data I checked, but there is now information about the input resistance. I'm wondering why this information is missing.
