Part Number: INA240

After de-cap analysis. The result is inconclusive. (No manufacturer's LOGO and DIE ID CODED which is not identifiable with the device number.)

Please help to advise if this is normal for this parts, thanks in advance

Carl,

The number to the right of the die "5541" does correspond to our die for this device, but I am verifying with our designers that this indeed our silicon. I will follow up once I hear back from them.

Carl,

I have heard back from our design team who have confirmed that this is indeed our die. Our die policies can shift depending on the size of the die and available space. Depending on the package we'll have at least a top side marking identifying the product. If the package is large enough we'll also have a lot/trace code, but most of our devices are small enough to where all we get is a the top side marking, here designated by the 5541.
