    Hey abhirv,

    Please post the circuit design here such that we can answer on that............

    Yes please post the circuit so that we can help.But from what I gather:You could probably connect the supply to a potential divider and the supply's ground as negative(of opam),the divider as ground and positive as positive of opam
