AD9234-LF500EBZ Analog inputs path

Question

Hello, 
 We are trying to use board AD9234-LF500EBZ to collect data during our experiments. 
 But standard analog input path does not allow us to convert DC component. High-speed converting of DC component is very important for us. 
 Is it possible to modernize analog input path of AD9234-LF500EBZ to convert DC component? If yes, how we can implement this? 
 
 Thank, Regards, Eduard

Hi Eduard, Thank you for your interest in AD9234. Unfortunately, the AD9234-LF500EBZ doesn't have a provision on the board to accommodate an amplifier for DC coupled applications. One possible way is to remove the presently installed AFE on the evaluation board and connect your amplifier prototype board on the available pads near the VIN pins. I'll list here some link of the related literatures related to your target application.
