I couldn’t locate one of the latter so relayed my circuit to use an LM instead, well it doesn’t work, i checked lm3090n 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: I probably have few AD’s around, but i dont think i have any LM’s around anymore.

Datashret them for other op amps probably wouldnt be much of a problem really. The LM is a high speed version. Maybe this was a very old design. Hi again, Yeah i remember these from back in the ‘s. Jameco has the LM’s: Datsaheet, Manuals or Parts. Hi, The LM was a very different kind of op amp.

Potentiometer Questions Started by norbss Yesterday at That’s what a specific timer of mine does. We can call the input resistor R1 and the resistor to ground R2 and the feedback resistor R3. 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.

The circuit uses a single polarity supply so grounding the non-inverting input of the opamps would cause their outputs to be grounded and they would work like rectifiers.

Electro Tech is an online community with overmembers who enjoy satasheet about and building electronic circuits, projects and gadgets. For one thing, the input bias would be different. One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff.

The LM is not a normal OP amp. Neil Groves New Member Nov 8, Articles Lm33900n Articles Search resources. Click here to register now. Forums New posts Search forums. It’s very different than the LM Media New media New comments Search media. It operates on the difference in input current rather than the difference in input voltages.

It would be possible however to change the design a little to use a more typical op amp. Welcome to our site! 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. Thread starter Neil Groves Start date Nov 7, It can not be replaced with a LM op amp. You must log in or register to reply here.

This may not be the ideal setup, but it might still work. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Hi, I’d be careful about using an AD for a replacement.

Is an LM a good vatasheet for an LM? From what i read, the NTE is a replacement. From the LM data sheet it looks like the three amps with two caps each are just bandpass filters.

For a better experience, please enable JavaScript in your browser before proceeding. The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground.

I am surprised to see them in circuits today. Roff Well-Known Member Nov 8, Thus you could look for the presence of line to speaker levels very easily and even filter the hiss.

The feedback resistor R3 is then: This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. Replacement Transformer Started by ncag 12 minutes ago Replies: To participate you need to register.
