Phase Splitter/Inverter with one input and two outputs, one in-phase and one inverted.
Both outs are at the same voltage as the source, so it is usable in a push-pull application or to bridge a stereo amplifier.
Please note that the input impedances of the following stages need to be matched, or grounded seperatly to be unattached by the input impedance.
IC may be TL072,LM358, 4558 or similar.
