Hi Sir,
I am looking for AS358MTR pin to pin replacement, I would like to propose LM358BIDR, is it suitable?
Is there any spec difference we should be care?
Thank you.
Regards,
Allen
Hi Allen,
I went through AS358 datasheet to make a comparison table to make it easier to compare. Now I couldn't find all the specs for the AS358 device so there's a few blanks in those columns but I did my best!
As you can tell both devices first appear similar but LM358B does have lower offset voltage and offset drift, quiescent current, shutdown current, and bias current according to both datasheets. The slew rate wasn't directly said in the AS358 datasheet but I derived it from the Voltage Follower Pulse Response graph which indicates it's lower than LM358B.
For the spec differences that you should care about, it really depends on what application the op-amp is going to be used for to determine key specs.
Let me know if you need any further assistance!
Best Regards,
Robert Clifton
