Opamp search

The National LM is a great chip. I just upgraded my Entech dac to the LM and put some film bypass caps on the supply rails In any cese, if there is one to be replaced, this is the one look for it between the two blue bands that drive the tape loop and record out selectors.


Personally, I prefer Texas Instrument’s Excaliber series. The other two, NJM are close relatives of the NE, one is used for tone control and is bypassed when these controls are not used.

Do you already have an account?

No, create an account now. The other is in the output stage but I am not altogether certain it does much more than DC and LF duty The LM does better through out the Freq range.

That’s about THE most common op-amp configuration. Share This Page Tweet. Your name or email address: No – the is a dual op-amp.

Thanks for posting this I was reading the specs on both chips. GibsonianJan 29, GibsonianFeb 3, Any of the plastic bodied DIP’s dataheet this group will work?

But does much much better from about 1kHz up for Distortion, noise, separation The bar continues to raise, which is good for the ears. Thanks for your help guys. I would like to compare. More clarity, just as much bass but tighter.

That is my opinion of course, you may want to compare a few to get the sound you like. Let me know your results, I may want to experiment with the LM as well.

Several sources make it. How about spec sheet on the C, know of where it can be dataheet I was surprised at the difference at datashedt, until I read the specs, then it all made sense I’m not too surprised by your findings. GibsonianJan 28, Mystic PixelJan 31, National Semiconductors LME49xxx line of op-amps have very impressive specs, but I haven’t tried them out yet I have recapped an older Denon PRA preamp and am hoping to replace the opamps inside to further improve this oldie but goodie.
