Default Amplifier +V, -V 0V

Hi all, this is not audio related but I figure the concepts are very much in the realm of everyone here and was wondering if anyone had an idea about it.

Basically, I'm trying to build a circuit that will take a high/low signal from a microcontroller and output either a +V, -V or 0V at relatively high power (approx 10A continious, 50V).

Any help is greaaaaaaaaaaaaaaaaaaaatly appreciated

Two bits for control.

+5 on bit 0 gets you v+ out

0 on bit 1 gets you v- out

o on bit 0 and +5 on bit 1 gets you 0V out

+5 on bit 0 and 0 on bit 1 gets you excitement.

probably want some source degeneration resistance on
the input devices to limit their drive current.

...and fresh underwear

technically, the 0V state is high impedance and will be whatever the receiving circuit pulls towards.
