OPA2347: WCSP-8/YZD Package Pinouts of OPA2347?

Hello Wenwei,

I do not see where in the OPA347 datasheet the pins are listed as A1, A2, A3, etc. Can you please provide what page or what figure in the datasheet shows this labeling?

Thank you,

Hi, Tim:

It is OPA2346, the dual part version of OPA347.

The first page shows the pinout view of the WCSP-8 package, which lists the pins as 1 to 8.

The last page of the datasheets shows the drawing of TZD-8:

Can I map these two unmatched pictures as:

Thanks.

Yes, that's correct.  OPA2347 is a dual version of OPA347 single and OPA4347 is a quad-see below.

Hi, Tim:

Can you confirm this?

Thanks.

Hello Wenwei,

I think it will be easiest to look for the pin 1 designator on the device package to determine the location of pin 1. Pin 1 is typically marked by a notch or a white dot on the package of the device. You will then be able to determine the location of pins 1 through 8.

Thank you,
