LM3886: Are the pins centered relative to datum A in drawing NDJ0011B from data sheet LM3886?

Hi Paul,

Thanks for your patience. We will get back to you by tomorrow.

Hi Paul,

Pin 1 is on the front row of pins. From the datasheet, this row is .169+.2 = .369 in from the back of the device.

Regards,

Ramsey

Thanks but I am looking for the location of pin 1 relative to datum A, given as the mid-plane of the tab width, not from the back (datum C)

.670 / 2 = .335  ?

Thank you. That does answer my question. I should ask as well whether the .150 hole is meant to be centered (coincident with datum A). There is no dimension locating it horizontally, and no part centerline from which to infer its location. 

For example in a similar drawing (NDA0011B, below) from the same data sheet, there is a centerline, highlighted yellow, locating the pins and hole.
