What is input resistance of the analog input for AD9231? Only the input
capacitance is given in the datasheet.
The input series resistance of AD9231 in track-mode is about 30 Ohms. Track
mode is where most customers will be concerned with the input impedance. You
can find more information in the S-parameter data file which is available on
the AD9231 product webpage, under the Evaluation Boards & Kits link.
