INA181: DBV package

Hello Naoki,

Thanks for coming to the forum to address your issue.

I am not sure what you mean when you say "If we don't order, there is no Pin 1 index?" There should be a pin 1 index. According to the datasheet there can be two variations: a marking in the pin 1 quadrant or a stripe from Q1 to Q2 (pin 1 to pin 3). This is the "OPTIONAL ORIENTATION MARKING" the datasheet is referring to.

I think the first pin 1 variation I mentioned may also be a stripe from pin 1 to pin 6, so customer should consider this a possible marking as well.

Please let us know if there is no pin 1 marking and send a picture of this as well.

Sincerely,

Hello Peter,

Thank you for your reply.

Yes, there is a stripe between pin1 and pin6.

Is this stripe pin 1 index?

I thought that the Pin 1 index is white circle or something.

Hello Peter,

I understood the Pin 1 index.
I will feedback the customer the information.

Thanks,
