I'm trying to find the pin #1 dot, on the ADAU1446 (100-Lead Thin Quad Flat Package [LQFP]). I have tried examining the package with a magnifying glass, but I just can't see it. Is pin #1 near the same corner as the AD logo? Is there any other way to determine the location of pin #1? Is the dot raised (i.e. a bump)? or is it sunk (i.e. a pit)?
