An apparatus comprising an amplifier and a switch network. The amplifier may be configured to generate a plurality of output signals in response to an input signal. The switch network may be configured to provide (i) a first path when a power signal is not present and (ii) a second path when said power signal is present. The first path may activate a first of the plurality of output signals. The second path may activate all of the plurality of output signals. An impedance may be connected to the amplifier only when the first path is activated.
