Lm3900 may not be the ideal setup, but it might still work. From the LM data sheet it looks like the three amps with two caps each are just bandpass filters.

We can call ml3900n input resistor R1 and the resistor to ground R2 and the feedback resistor R3. That’s what a specific timer of mine does.

It would be possible however to change the design a little to use a more typical op amp. The feedback resistor R3 is then: Hi again, Yeah i remember these from back in the ‘s.

From what i read, the NTE is a replacement. Replacement Transformer Started by ncag 12 minutes ago Replies: For a better experience, please enable JavaScript in your browser before proceeding.

I am surprised to see them in circuits today. One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff. Lm3900h, I’d be careful about using an AD for a replacement.

Hi, The LM was a very different kind of op amp. Potentiometer Questions Started by norbss Ml3900n at 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 datashset work the way you want it to.

It can not be replaced with a LM op amp. For one thing, the input bias would be different. Back in the 80’s i did.

Datashert 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: Is an LM a good replacement for an LM? Thus you could look for the presence of line to speaker levels very easily and even filter the hiss. Media New media New lm3900h Search media.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Roff Well-Known Member Nov 8, Maybe this was a very old design. It’s very different than the LM Redesigning them for other op amps probably wouldnt be much of a problem really.
