This package is not a metric pitch SOP. 

It is a 50 mil pitch SOIC. 

The Polarity Marker is a Chamfered Body along the entire upper edge of Pin 1.

It is an SOIC-8. The Analog Devices R-8 package.

Here is a link to a part that uses that package.

Is this for the SOP component family? 

We need the URL link to the datasheet so we can reproduce the error.

When I export my part to Altium there is no white dot on the 3D model as show here.



Thoughts?
Thank you.
