Long shot I know but does anyone know of an online source document that explains the manufacturer codes used for op-amps.

Ideally I would like a simple summary such as what letters are used for temperature ratings or package type.

I've talked with Mr. Google and been to the TI and National Semiconductor site but can't find a simple overview document.

Do you know the manafacturer???

Try the RSComponent website ...... their DataFiles are good reading!!

It may help!?

I was hopeful of getting a "general" overview somewhere Mr. Chief. As Pete says I can always wade through all the data sheets for each family and extract the information but as you know that will take for ever. Even if I could get the info for any one manufacturer then it would be useful though.

I have been to RS Pete and, that I can see, they don't do a summary document, which is what I am after.

And I thought this would be simple!

well what do ya wanna do with the op amp??

Oh, I don't want to do anything with a specific one at present. I am roped into providing a list (or at least a partial list) of what the manufacturers codes mean in general terms. I thought it was the work of 5 minutes and a quick Google search. How wrong could I be!! However, there must be such a list available somewhere. I can't even find a manufacturer specific one on the TI or National Semi sites.

I dont know if this is any good but if not then ignore it!

There's no general rule or consensus, every manufacturer has its own codes and even they vary from device to device or even package to package.

This page may help for TI - often manufacturers have specific 'packaging info' pages which include this sort of data, or you can just look up the data sheet for a particular device of interest and it'll give you the ordering information.

Sometimes you do get nice easy tags like 'C' for commercial temp range and 'I' for industrial, but don't rely on it. 'Z' sometimes means lead free.

Thanks for that, it is another good source of info and one that I hadn't found.

I wish there were somewhere with a table but as everyone does it differently I guess a summary is tricky to pull together, as I am finding out. Oh well.
