I have questions about NC pin of OPA859. OPA859 pin2 is NC, means not connect, datasheet explain user not connect this pin to any circuit. But nc has a little ambiguous meaning for user, is nc means opa859 internal not connect or second meaning is user not connect nc pin? Is there any internal connect or circuit in nc pin of opa859? I carelessly wired the NC pin to ground with Vs+=+5V and Vs-=ground, is this will damage opa859 or cause opa859 not work correctly?
