DDC264: Floating inputs

Part Number: DDC264

Hi Guys,

Greetings to you. Could you help us check our customer's concern on using DDC264 chip in one of their designs. Main concern is they do not need to get recordings from all the 64 channels.

They wanted to know If leaving some DDC inputs floating may affect the recording quality of the remaining channels (which are normally connected to the sensors).

They are thinking one solution if possible and this is to connect each of the "floating" inputs to a 10MOhms resistor and then to ground (or directly to ground without the resistor, but maybe this will not work).

We are hoping for any suggestions or solution to this query. 

Thank you in advance for the support. 

Best regards,

Jonathan
