I am attempting to authenticate an AD7703AN ADC for a client, and I want to be certain that I am using the correct package dimension reference for our inspection.
The device is a PDIP package marked with a 9539 date code, with outline dimensions that match 'Figure 18. 20-Lead Plastic Dual In-Line Package Narrow Body (N-20)' diagram from the AD7703 datasheet REV F, revised in 2019.
However, I also have REV E of the datasheet (revised in 2003) and REV D (revised in 1996), in which the PDIP outline dimensions do NOT match the device being inspected.
I'm attempting to locate REV C of the datasheet, to check the dimensions against the correct package diagram from when this device was produced. I am coming up empty handed though, and was wondering if there is a repository of archived Analog Devices datasheets that are publicly available somewhere. I suspect the device package is not authentic based on what I am seeing, but I would like to be completely certain if possible.
