ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?
Just leave the NULL pins floating or "NC" in your case. Frequently Asked Question | Analog Devices
You're welcome. I once used ADA4627-1 in one application circuit that I worked on. I just left the NULL pins hanging and the part just worked well.
Thank you for the reply.
