My customer will use ADA4310 and is designing his cirucit.
Then he would like to get input impedance of ADA4310 for designing front end ( around signal source ) of ADA4310.
Datasheet P4 says below.
Input Resistance f < 100 kHz , Typ 500 kΩ.
If there is any information about input impedance > 100KHz, could you give me your advice ?
For your information, my customer input ~50Mhz signal to ADA4310.
