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.
