We are designing with your ADC AD9432 for our product.
So I have a question.
As for your datahseet page.15 Fig-29 my enclosed, I can see the matching resister and capacitor between AD8132 amp and AD9432 AIN and AIN/.
1) 50ohm and 22pF, where can you bring these values?
2) And what are the input impedance of AINs?(3kohms on your datasheet analog input resistance , correct?)
I think that 50ohm and 22pF came from above 2)inout resistance.
If I connect AD8132 to AD9432 directly, what trouble will happen ? Oscillation?
Please let me know why are 2-50ohms and 22pF there?
