what is difference between OP AMP and differential amplifier?

Answer Posted / rajat jain

a little bit modification to above answers-
An opam is an amplifier designed to perform specific
operations such as
subtraction,addition,integration,differentiation,log,antilog
etc. A diff. amp is a part of opam. And opam can also
function as differene amp; which amplifies the difference
of the two signals.
