(Datasheet) LM pdf – (LM / LM / LM) Quad Amplifiers (1-page)
Neil Groves New Member Nov 8, You must log in or register dataasheet reply here. From what i read, the NTE is a replacement. Hi, I’d be careful about using an AD for a replacement. Is an LM a good replacement for an LM?
That’s what a specific timer of mine does. Welcome to our site!
For one thing, the input bias would be different. Articles Top Articles Search resources. Maybe this was a very old design. Roff Well-Known Member Nov 8, To participate you need to register.
I am surprised to see them in circuits today. The Q of each bandpass lk3900 be a little higher fatasheet so you’d have to try it and modify the values slightly if it doesnt seem to work the way you want it to.
Back in the 80’s i did. The feedback resistor R3 is then: One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff.
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: Hi again, Yeah i remember these from back in the ‘s.
The LM is not a normal OP amp. Datasheets, Manuals or Parts. Media New media New comments Search media. It operates on the difference in input current rather than the difference in input voltages.
Thus you could look for the presence of line to speaker levels very easily and even filter daatsheet hiss. It can not be replaced with a LM op amp.

This may not be the ideal setup, but it might still work. The circuit uses a single polarity supply so grounding the non-inverting input of the opamps would cause their outputs to be grounded dagasheet they would work like rectifiers.
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 ,m3900 using a dataeheet circuit. Redesigning them for other op amps probably wouldnt be much of a problem really. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Thread starter Neil Groves Start date Nov 7, Replacement Transformer Started by ncag 38 minutes ago Replies: Jameco has the LM’s: Neil Groves New Member Nov 7, It dataeheet be possible however to change the design a little to use a more typical op amp.

I probably have few AD’s around, but i dont think i have any LM’s around anymore. From the LM data sheet it looks like the three amps with two caps each are just bandpass filters. The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground.
Hi, The LM was a very different kind of op amp. The LM is a high speed version. It’s very different than the LM
