I need to build a circuit that either takes +30Vdc in and spits out -12Vdc'ish and +12Vdc'ish, or inverts the +30Vdc into an ac wave form large enough that I could bridge it down to -12Vdc'ish and +12Vdc'ish. (Gotta power an op-amps circuit that simply will not play nice with biasing the inputs. But works like a dream with a split voltage ps.) I would prefer the former, but either way would work. Only need about 150mA-200mA max of the split voltages, can go as low as 9Vdc, and as space and efficiency is not an issue I have no problem filtering the mess out of a nasty ac waveform if needed. What should I be looking for? (I know just enough about electronics that I know I don't know enough, I can only take so many electronics engineering classes at a time and work a 40 hour regular work week...)
