The pin should be connected to the reference voltage for the single ended output. In other words, if you want the voutput voltage to be with respect to +2V, you would connect the pint to a +2V reference. If you want the output voltage to be with respect to ground, then connect the pint to ground. If you connect it to a voltage other than ground, you must be careful not to exceed the input common mode voltage range of the op-amp.
