Diff-amp is basically designed as DC-amplifier so that it
will be suitable for IC fabrication .Also the lower
frequency response is also improved.Taking i/p as
difference of 2signals is required so as to eliminate noise.

Diff amp is one of the stages of the Op-amp.Op-amp is
having very high gain which is obtained by using diffamp
transistors as darlington pair and their gain beta is
increased by punch through effect.
