Have a dual channel opamp, only using one of the channels. Should I ground both the inverting and non-inverting inputs, ground the non-inverting input and tie the output to the input, or what?

What I've typically seen is to wire the unused as a non-inverting buffer.
So, wire Vp(+) to com, Vn(-) to output.

I'm sure there are many other safe ways.

 

Thanks, I was coming back to post that after thinking about it it would be a bad idea to wire both inputs to ground because of the loss of feed back But ya beat me to it by a couple minutes
