In the past, I've had some hissing problems with low-impedance phones and my MINT amp.
- I'm not sure if it's oscillation, so how would I measure it with my o-scope?
- If it is oscillation, would adding bypass caps to the opamps get rid of the noise?
- What values should I use, and what configuration - rail to rail or rails to ground?
- I've been reading on the issue, and it seems some people recommend both a low capacitance ceramic parallel with a high capacitance film or electrolytic. Is the high capacitance cap necessary? Also, is it plausible to share the high capacitance cap between several opamps?
- Would buffers benefit the same way?
