The high common-mode input voltage range and the absence of latch-up make these amplifiers ideal for voltage-follower applications. The devices are short-circuit protected and the internal frequency compensation ensures stability without external components. The D packages are available taped and reeled. Add the suffix R to the device type e.

Welcome, Guest. Please login or register. Did you miss your activation email? Home Help Login Register. Author Topic: LM? Read times. What is it? A quad opamp or? Is there an equivalent chip for this? I couldn't find any technical data on it on the web and NTE electronics doesn't have it in their cross reference, either Can I get a little help here, please?!? Punch RC into google and there are some data sheets for this quad opamp. So I could probably use a quad opamp that I have lying around.

I have a quad lying around also and have not an idea what to do with it. Not too bad a mistake at 1. Something about intermodulations makes these quads less desirable for some usualuses I read. Looks good, lie a but lower noise, wider voltage range, better behaved.

BUT, wacky pinout!! It's used in the Electronic Projects for Musician's book. Not as rare as a , but not as common as a couple of s I have several TL's, I figure I'd try one and see how it works. The only sub for the is a TL which is very hard to find as well. You might have to do the "dead bug" replacement that RG has on his site. Anyway, if you need them, there they are!

Mark Hammer more Poster2 Posts: Total likes: The LM and I think other companies produce them as well is nothing special, simply a quad op-amp with decent noise characteristics though not exactly in the OP or even NE category.

As low noise stuff went in the late 70's it was probably the most convenient package, and certainly prived better - per op-amp - than anything in the same noise-spec class at that time. As was pointed out, the TL will sub for it with respect to pinout, though the TL has a much higher input impedance.

As was also pointed out, the TL is especially hard to find. Jay Doyle Guest. Without starting a "mojo"storm, the LM is the quad version of the SMF 2.
