Integrated Circuit (IC) identification & Datasheet

Hi Everybody

I have 2 Nos. IC's that I can't find their data nowhere. I would be grateful if someone could help.

(i) IC No. 1 - Top Marking: 324 AND Bottom marking eZ5A827. It is an IC from STMicrolectronics as per the logo

(ii) IC No. 1 - Top Marking: 358 AND Bottom marking eZ835. It is an IC from STMicrolectronics as per the logo

Thanking you in advance.

You're assuming that IC's have meaningful numbers - often this isn't the case - it's common practice for equipment manufacturers to order parts with 'in-house' numbers which are totally meaningless (other than to themselves), and datasheets aren't available because those don't exist.

If you need replacements, the only source is the equipment manufacturer.

324 and 358 are both generic types of opamp, from many manufacturers

It could be those - or as Nigel says, they could be in-house numbers and totally different...

See if the power pins & anything else traceable match up with the data sheets?

Thanks everyone for your kind consideration and help

Yes, infact it is LM324 & LM358.

If you can not unmask your ic in question then you can still usually find a lot of masked clone versions on ali. Hit or miss if they get it right or not but usually they do.
