ca 1972 RCA had a thick film hybrid HC2000 that was rated at 100 Watt out=

with. Neat idea but wasn't quite what I needed.

Does that count? I'd call that the precursor to the STK modules, but not
really an IC since it's not monolithic.

The first monolithic I remember was the CA3020, also from RCA around then, but
I wouldn't be surprised if there were some before it.
