Hi Team,

I am using AD7655ASTZ. It has 4 data input pins, and I require one input channel from it.

As these are analog input pins and can not be left floating, which of the following is the better option to connect these pins?

1. With any specific value of capacitor to ground.

2. Without any capacitor and directly connect to ground.
