Ref is the input reference voltage (can be connected to circuit common, or to one side of a differential input for differential input signal for common-mode signal rejection).

Sens is for the negative feedback (typically connected to the output).

 

what is the difference between connecting feedback to output and connecting feedback loop to sense?
Thanks.
