ultrasonic 5532

[nss at hevanet.com]

Hello list!

	Well I'm glad I was paying attention to the talk about op-amps going
into ultrasonic oscilation, as I would not have recognised it otherwise!
I made a $10 harmonic sweetner/compressor and one of the 5532's decided
to mess with me. It was ultrasonic, how ultrasonic? Don't really know,
my 500khz Heathkit 10-12 could not keep up with it...
	But anyway, question: I got rid of it by bypassing the power supply
closer to the offending chip. Is the osc caused just because of power
supply leads, or does having high impeadence feedback(high gain) paths
have somthing to do with it? Will they still do this sometimes when
hooked up as unity gain inverters?

	Just wondering... now
