Part markings for SOIC 8 chips

I cannot seem to find any reference on AD's website for small part markings.

I have some ADR430ARZ chips but I am trying to decipher the date code. Is anyone able to tell me what the markings on the top and bottom of my chip are? Some are obvious... like ADR430... and PHIL. But the rest I am unsure.

TOP:
ADR430
A#117
9234
BOTTOM:
#117
2109234
PHIL
