With a pair of opamps and a built-in voltage reference the LM10 is a very versatile IC which is clearly brought forward in the datasheet in which numerous application examples are provided.

No publicly available high-resolution die shot of the LM10 seem to exist. A very low resolution preview is shown in one of the designer's research paper [1] as shown in the below image. In [2] another picture reveals part of a mask drawing of the same IC, which can clearly be recognized as being the same.

Luckily, a military grade metal can version is available and can be de-capsulated somewhat easier than a more modern plastic package. A small metal pipe cutter intended for car brake line cutting is used to cleanly remove the top of the metal can. Sometimes similar metal can packages are filled with various materials including sand or epoxy which may require cleaning up the die. This was not the case for the LM10.

With this new much higher definition die image it can clearly be seen that the top metal layer corresponds to the mask drawing visible in Widlar's Wikipedia picture [https://en.wikipedia.org/wiki/Bob_Widlar]. Upon close inspection some minor differences can be spotted, so the mask in the picture is probably a revision A whereas the die shows a revision B mask in the lower right corner. Can you find some interesting changes?
