LM144H

Hi Everyone,
Anyone has a copy of the National semiconductor LM144H Data-sheet? I tried e-mailing National Semiconductor, without success.
Thank you,
Eric

There is some info at datasheetarchive.com
The part is obsolete but I believe the uncompensated version is the LM143.

Here's a datasheet from 1995 -- the part is not in the National Linear Databook for the same year.

Thank you for your quick replies, I was hoping to find a more complete datasheet for my project posted here.

70W Class A amp.

At the end, I had to use a different OP-Amp successfully, using the information in another magazine article.

Could it be the industrial/mil version of LM344/LM344AH?

Actually, I think it is the military version.
