    I've been waiting a long time for this.

    Note that it requires "extreme care when handling". :rolleyes:

    Forgot to add in the datasheet "Self generate Earths entire energy needs, simply
    connect your grid to P_all_earth pin for fulfillment".

    Regards, Dana.

    Hi,

    There is such a thing in theory though though the transfer function:
    limit F(s) as A goes to infinity
    where A is the gain of a voltage controlled voltage source used in place of the op amp.
    The result is the circuit with an op amp that appears to have infinite gain and no input current, etc., and no needed power supply and unlimited output current.

    Well of course it does, since it can output infinite voltage and current!
