It operates on the difference in input current rather than the difference in input voltages. Is an LM a good replacement for an LM?
Replacement Transformer Started by ncag 38 minutes ago Replies: I am surprised to see them in circuits today. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Maybe this was a very old design.

Thus you could look for the presence of line to speaker levels very easily and even filter the hiss. The feedback resistor R3 is then: To participate you need to register.
It’s very different than the LM Back in the 80’s i did. Roff Well-Known Member Nov 8, It can not be replaced with a LM op amp.

Click here to register now. 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. Hi, I’d be careful about using an AD for a replacement. Media New media Datashedt comments Search media. Articles Top Articles Search resources.

Thread starter Neil Groves Start date Nov 7, This may not be the ideal setup, but it might still work. Hi again, Yeah i remember these from back in the ‘s.

Electro Tech is an online community with over datashet, members who enjoy talking about and building electronic circuits, projects and gadgets. One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff.
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 darasheet to it using a different circuit. You must log in or register to reply here.
Potentiometer Questions Started by norbss Yesterday at Datasheeet to our site! Hi, The LM was a very different kind of op amp. 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.
From what i read, the NTE is a replacement. Jameco has the LM’s: Redesigning them for other op amps probably datasheft be much of a problem really.
