[sdiy] Discrete Op Amps

[cheater00 cheater00]

Every load of bullshit starts as truth that gets twisted and facsimiled. So
let's pick out what might be true.

He says that the single transistors in a monolithic IC op amp can dissipate
much less, so their gain is lower, and therefore there must be many more
stages. Can this be true?

My guess is also that control (feedback) topology ends up being much more
complicated, resulting in less pleasant edge cases (ie what happens when
the op amp reaches an unusual or extreme state). Is feedback topology a
large issue in op amps like it is in amplifier circuits? Does using more
stages make this problem bigger?
