hi,
thx for replying,
actually , i was being taught abt op-amps at college, when my Lect told me that it has 4 stages, first two being Diff Amps the third being an impedance matching ckt and the fourth, a level shifter...
and gave some explanation for the impedance matching unit ,which i cudnot understand and could not accept ( he said that impedance mismatch could cause more current 2b drawn by the load,which a CEA cannot provide(of course) and so we impedance match
so i set out on a meaning hunt...
now tell me, does the op-amp have Imp Matcher, or not?
and if u have any other comment about the above mentioned str of op-amp,tell me,i am all ears,
and is there anything important i must know abt op-amp,
I WANTED TO USE IT AS A COMPARATOR FOR A LINE FOLLOWER..
so i wanted to know more abt it
Thx
