AD8250 has differential input impedance of 5.3Gohms/ 0.5 pf.
I have input signal whose differential input impedance which is driving AD8250 is 10Mohms & 5pf.
My customer is saying that i may not be able to give differential signal to AD8250 directly as there will be impedance matching problem.
What i understand that AD8250 has good input impedance of 5.3Gohms. But only problem is 0.5pf. How this matter to my my input signal ?
1. Will there be loading ?
2. Do i need to match AD8250 input capacitance to the input signal requiremnt ?
3. How can i match that ?
Please answer for above questions.
