Part Number: LM224
Hello, We have two lots of LM224DR ,and found different wire bonding. is it normal?
Hello,
Yes this die has transitioned to a new fab., see the PCN below:

Since the die is smaller and has different bond pad locations, it is expected that the wire bonds will also look different. So this is expected, there should be no problem with the new material.
Regards,
Mike
