How do I identify Pin 1 on a chip with no corner mark
If you dig a little deeper on the Maxim website, there's a package drawing for this part.

Pin 1 is clearly indicated.



Note 8 says: "MARKING IS FOR PACKAGE ORIENTATION REFERENCE ONLY", which means AAAA is boilerplate text.

Essentially, if you can read AAAA, pin 1 is lower-left.
