Learning about op amps and their various power options:
- With dual supply, are we talking Vcc+/Vcc- being AC signals, or just constant DC voltages (positive/negative)?
- If the latter, then how is the negative voltage typically generated? Does it require an AC signal, or can it be done using a positive DC voltage as well?
- Sometimes I see this variation where either Vcc+ and/or Vcc- are run through capacitors or other components. Are there any major advantages/disadvantages of incorporating that sort of thing into a circuit design?
- Are there any "universal" methods for converting a dual-supply circuit to a single-supply design, and vice-versa?
