Hi!

I'm looking for a LM358 CMOS OP-AMP but have only found a LM358 DIP8.

Can someone tell me the différence?

Thank you! :)

DIP8 is a package type. It stands for Dual In-line Package with 8 pins.
CMOS is a semiconductor fabrication technology. It stands for Complementary Metal-Oxide-Semiconductor

I don't think the LM358 comes in a CMOS version, so your search is likely to be fruitless. Never fear there are plenty of CMOS opamps that you can use regardless of your application.

Your question is like asking the difference between an orange and a bicycle.

LM358 is a BJT op-amp, not CMOS.

DIP8 is the package style.
LM358N, LM358P, LM358AN is the standard 8-pin thru-hole 0.1" spacing, 0.3" width package.

As has already been mentioned, DIP is a package and CMOS is a process technology.

Why do you think you want a CMOS opamp? It would be helpful if you described your application requirements.

All of the CMOS opamps I've looked at have much smaller supply voltage ranges than bipolar opamps and that has limited my usage. Plus the cost when an LM358 will do.

The good news is that there are many dual opamps in 8 pin packages with the identical pin-connections as the LM358. And if you spend a bit more you could get an LM258, which has a wider temperature range.

Ok, thank you, your answer doesn't surprise me, that's why I wasn't understanding anything at it
So it is probably an error in my list of component...
Thanks again!

Thank you Dennis, thank you for your details... I thought I needed this because it is written like that in my list, but I think now it is just an error.

Ok, thank yous o the only difference between a 358 and a 258 is the temp range? ... I was also wondering.

The CA3240 is a full CMOS, dual opamp (like the LM358), which can be supplied all the way to +/-15 volts. Again like the LM358. It is practically a drop-in upgrade to the LM358.
It is also available in a DIP8 package, but be warned that DIP packages are disappearing fast, the industry is moving towards all SMT packages, like SOIC, SOP, and others.
