opamp question..... JRC386D and LM386

[plexi12000]

i was wondering if these two IC's are the "same"?  the "prefix" letters are just the manufacturer, correct? thanks

[Kipper4]

What do the data sheets say?
Same? Similar? way off?

[dschwartz]

Jrc are reportedly more stable (less prone to oscillation)  than the lm ones..

A '386 is either an old CPU or the most popular audio amplifier.

LM386 was the original. JRC (New Japan Radio, now under another name) made an awful lot of them, and maybe better than most other 2nd-sources.

___D is JRC's mark for 8-DIP, which is surely the package you want. This grade is rated for 12V operating, 15V ab max.

thank you, boys.   -Kipper, yeah i dint think of a 'data sheet'.  i guess every electronic componant has one?

Pretty much, yup! Sometimes the sheets for very old stuff can be hard to find (like, a certain vintage vacuum tube, etc...) but for 99.9% of what we use on our boxes, you should come up with something useable by Googling the part.... "LM555" would result in like 10,000 hits, etc   You may have to sort thru them at times to find a "good one", but they're not that hard to find.  More popular parts will have more, clearer sheets...
