Title: CA3080 Replacement
Post by: MRTelec on January 23, 2004, 08:16:06 PM
Hi,

I'm building a compressor and my supplier is out of CA3080s.  What's a suitable replacement for this part?  I searched the archives but couldn't find an answer.

Thanks.

Although you can use an LM13600 r 13700 as a suitable replacement OTA for design purposes, neither of these willsimply sub for a 3080.

Do note that the LM3080 is the same thing as a CA3080, just a different manufacturer.  Most supply houses will be astute enough to recognize that there is no difference, but it wouldn't be the first time I've seen someone look up stock on a part using the prefix as a core part of the search string to the complete neglect of equivalents bearing other prefixes.

I'm assuming there is an NTE/ECG replacement but I don't know the number.

Thanks for the help.  I was hoping to order it from Digi-Key along with my caps, but they don't have anything.  I'll put together an order for Small Bear.
