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 daasheet to it using a different circuit. Datasheets, Manuals or Parts.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at From the LM data sheet it looks like the three amps with two caps each are just bandpass filters.
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
I couldn’t locate datasheeh 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: We can call the input resistor R1 and the resistor to ground R2 and the feedback resistor R3.
Hi, I’d be careful about using an AD for a replacement. Hi again, Yeah i remember these from back in the ‘s.

Maybe this was a very old design. 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.
The LM is not a normal OP amp. Articles Top Articles Search resources. Back in the 80’s i did.
Roff Well-Known Member Nov 8, Potentiometer Questions Started by norbss Yesterday at From what i read, the NTE is a replacement. It can not be replaced with a LM op amp. Media New media New comments Search media.

Replacement Transformer Started by ncag 38 minutes ago Replies: One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff.

It would be possible however to change the design a little to use a more typical op amp. For one thing, the input bias would be different.
The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground. Neil Groves New Member Nov 8, Forums New posts Search forums. Welcome to our site!

I probably have few AD’s around, but i dont think i have any LM’s around anymore. This may not be the ideal setup, but it might still work.
