I really appreciate the info. The price for the 14 pin 741 is too high and makes no sense. I have decided to modify the board and use the $0.30, 8-pin IC, instead of the 14 pin device for $128.00
How many pieces do you need? I might possibly have one or two that I can spare.
Where can I purchase uA741 op amp in 14 pin dip package?
The 14 pin DIP (P/N: UA741MJ) is no longer manufactured, but may be found on surplus sites.
OR…
The following company (Rochester Electronics) specializes in sourcing obsolete integrated circuits, and has 1,938 of them them available for sale, but you may be surprised at the price you will have to pay… If you need more, they can PRODUCE them for you. I don’t know what their minimum purchase for production would be.
Thanks a ton for d help! Really enjoying doing this 🙂 I like dis site ..
Thank u for your nice information
Comment
thanx 4 this type implementation
Following my earlier comments re pin numbering of the 741 opamp the above is obviously referring to the most common 8 pin DIL package.
Suggest that in all circuit diagrammes involving the 741 opamp the pinout is as per the above.
Note : I really enjoy this web site ; thanks P.Marian !

Also note that back in the ’70s there was a 14pin version–I think I still have a few kicking around–probably now a collector’s item…

Thank you very much for your appreciation!
nice data sheet but extra not describe . Extra
Yes an interesting simple project to implement . However the pin-out of IC1 (741 opamp) is NOT as per the 8pin DIL layout in the data sheet
It might be wise to correct the circuit diagram 741 pin-out

thanks for ur information
