National Semiconductor – datasheet pdf
Roff Well-Known Member Nov 8, The LM is not a normal OP amp. To participate you need to register. Click here to register now. You must log in or register to reply here.
It can not be replaced with a LM op amp. Is an LM a good replacement for an LM? Datasheets, Manuals or Parts. It’s very different than the LM Articles Top Articles Search resources.
That’s what a specific timer of mine does.

The feedback resistor R3 is then: The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground. I couldn’t locate one of the latter so relayed my circuit to use an LM instead, well it doesn’t work, i checked my output from the first stage and it sits at 10V although the input is a 4V p-p sine wave from my generator, i am building the circuit here: From what i read, the NTE is a replacement.
I seem to have blown out on at least two things here, i’m gonna scrap that project, build something else i need then come back to it using a different circuit. Back in the 80’s i did.
I am surprised to see them in circuits today. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
Hi again, Yeah i remember these from back in the ‘s. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Replacement Transformer Started by ncag 59 minutes ago Replies: Neil Groves New Member Nov 8, Maybe this was a very old design.
km3900 It would be possible however to change the design a little to use a more typical op amp. The Q of each bandpass would be a little higher though so you’d have to try it and modify the values slightly if it doesnt seem to work the way you want it to.
