I have a circuit board I pulled out of something and it has several of these SJ4558 chips on it. I 'm wondering if they can be used as a sub for LM386 chips for making small amps? , Or would it just be false economy even if they "should" work? Looking forward for suggestions please.
In short terms, no. The 4558 has 8 pins like the LM386, but that is the only thing these two IC chips have in common.
Thank you!
LM386 chips are 10 for a dollar on ebay. While the SJ chips could be awesome chips, unless it is a topic you find worthy of personal interest there is no economy in it.
Thank you, that is what I figured.
like others have said the 4558 is a dual amp. it can be used instead of a LM358. they have the same pinout but may have different gain.
a LM386 is a single amp with a different pinout and vastly different curcuit, so no it cant be a substitute.
Thank you!
OK, wow, thanks for all the info! I'm not THAT motivated!
Thank you!
I did salvage some capacitors that should work as they are the correct numbers.
