Bypass caps (was:Re: [sdiy] Silly question about dual vs. quad op amps

[limor]

adding -too many- caps is not necessarily a good idea and its
certainly a waste of money. lets be reasonable, people: a single .1uF
ceramic cap per IC is just fine unless there are multiple power lines
and the datasheet requests more. and, for high-current spike ICs, a
2uF tant or 20uF electrolytic for every 3-5 ICs to reduce resonant
ringing on spikes (Pease, pg 45)
