Zeptobars posts a dual op amp, LM747CN, with a date code of 8852. The manufacturer is unclear.
While some 747 designs mention that “two amplifiers share a common bias network” – here we see 2 independent identical mirrored op amps.
The die size 1545 x 987 µm. You can find the data sheet for this chip here.
See the full die shot details on the Zeptobars website.
