      … your reply. The provided information is really helpful to me. As you suggested I have decided to use ADA4941( similar to ADA4940 ). I am using ADA4941 (single to differential converter) as similar to the architecture suggested in the datasheet of AD7982(Page:15, Figure : 26). The datasheet of ADA4941 doesn …

      Hello, I am getting data from an AD7961 ADC with an ADA4941-1 in front as a single-ended-to-differential stage. I am getting a surprising noise of +/-2mV when I short the ADA input to ground. This noise goes down to +/-0.2mV if I skip the ADA4941 …

      Hello I am considering Sallen-Key, Low-Pass Filter like figure 54 on the datasheet. There is a situation that the input is opened. Then the output would be unstable. Should I put termination resistor? If yes, which value can I use? There is a little oscillation at output because …
