Yes, my password is: The National LM is a great chip. I would like to compare. Share This Page Tweet. You must log in or sign up to reply here. GibsonianFeb 3, GibsonianJan 29, GibsonianJan 28, Your name or email address: Thanks for posting datasheer In the phono circuit some real oldies, uPCC’s, u is micro I cannot find any info.


The other is in the output stage but I am not altogether certain it does much more than DC and LF duty Datadheet was surprised at the difference at first, until I read the specs, then it all made sense Personally, I prefer Texas Instrument’s Excaliber series.

Thanks for your help guys. The bar continues to raise, which is good for the ears. Anyone have any info. No, create an account now.


I was reading the specs on both chips. Let me know your results, I may want to experiment with the LM as well.

Opamp search

The other two, NJM are close relatives of the NE, one is used for tone control and is bypassed when datasheer controls are not used. National Semiconductors LME49xxx line of op-amps have very impressive specs, but I haven’t tried them out yet The LM does better through out the Freq range. That’s about THE most common op-amp configuration.
