OPA2134: OPA2234UA

Chris Guo

Part Number: OPA2134

Anyone had experience on this part marking? what's the " 1" "2" or "A" on the first line stand for?

Does the "A" is for suffix UA for the part number?

thank you!

Hello Chris,

The 1 and 2 are obsolete. The A was for a grade out difference in the past. Please see this post as well that provides further details.

Best Regards,

Hi Chris,

Can you forward the post you have mentioned? In addition, Does the OPA2234UA and OPA2234U has different markings?

Hi Chris,

The U and UA were different grades of devices. Sorry I forgot to paste the link.
