Is an LM a good replacement for an LM? Hi again, Yeah i remember these from back in the ‘s.

LM substitute? | Electronics Forum (Circuits, Projects and Microcontrollers)

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at To participate you need to register. Maybe this was a very old design.

From what i read, the NTE is a replacement. Articles Top Articles Search resources. Welcome to our site! Hi, The Ratasheet was a very different kind of op amp.

For one thing, the input bias would be different. Neil Groves New Member Nov 7, The LM is not a normal OP amp.


Thus you could look for the presence of line to speaker levels very easily and even filter dayasheet hiss. That’s what a specific timer of mine does. 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. It operates on the difference in input current rather than the difference in input voltages.

The feedback resistor R3 is then: It would be possible however to change the design a little to use a more typical op amp.

It’s very different than the LM Thread starter Neil Groves Start date Nov 7, Redesigning them for other op amps probably wouldnt be much of a problem really.

Neil Groves Datasheet Member Nov 8, Roff Well-Known Member Nov 8, 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 LM is a high speed version. The non-inverting inputs dwtasheet connect to half the supply voltage filtered with a capacitor to ground.

Potentiometer Questions Started by norbss Yesterday at It can not be replaced with a LM op amp. One of the cool things about the LM is that the input dattasheet can exceed the supply rails without a lot of fancy stuff.
