Jameco has the LM’s: You must log in or register to reply here. Hi, The LM was a very different kind of op amp. I am surprised to see them in circuits l3m900.

The LM is not a normal OP amp. Welcome to our site! From what i read, the NTE is a replacement.
This may not be the ideal setup, but it might still work. The non-inverting inputs should connect to half the supply voltage filtered with a capacitor to ground. Hi again, Yeah i remember these from back in datzsheet ‘s.

The feedback resistor R3 is then: It’s very different than the LM It would be possible however to change the design a little to use a more typical op amp. The LM is a high speed version.
Roff L3m900 Member Nov 8, Maybe this was a very old design. From the LM data sheet it looks like the three amps with two caps each are just bandpass filters. 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 lj3900 work like rectifiers.
Replacement Transformer Started by ncag 59 minutes ago Replies: Hi, I’d be careful about using an AD for a replacement. For one thing, the input bias would be different.

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 datssheet although the input is a 4V p-p sine wave from my generator, i datasheeet building the circuit here: 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 operates on the difference in input current rather than the difference in input dataaheet. Neil Groves New Member Nov 8, Media New media New comments Search media.
I probably have few AD’s around, but i dont think i have any LM’s around anymore. That’s what a specific timer of mine does. Forums New posts Search forums.
