Quadruple Operational Amplifier

The feedback resistor R3 is then: I probably have few AD’s around, but i dont think i have any LM’s around anymore. It can not be replaced with a LM op amp.

The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Hi, The LM was a very different kind of op amp. Hi again, Yeah i remember these from back in the ‘s. The LM is not a normal OP amp. Neil Groves New Member Nov 7, I couldn’t locate one of datasheeg 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: Redesigning them for other op amps probably wouldnt be much of a problem really.

Hi, I’d be careful about using an AD for a replacement. It’s very different than the LM I am surprised to see them in circuits today. Back in the 80’s i did. 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 lm3900h different circuit. It operates on the difference in input current rather than the difference in input voltages.

We can call the input resistor R1 and the resistor to ground R2 and the feedback resistor R3. 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 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. Jameco has the LM’s: Maybe this was a very old design. Is an LM a good replacement for an LM?

This may not be the ideal setup, but it pm3900n still work. Potentiometer Questions Started by norbss Yesterday at To participate you need to register.

From the LM data sheet it looks like the three amps with two caps each are just bandpass filters.
