hi,i need a circuit and information for 5th order low pass filter using ic lm741.
thanx
 

Try cascading two second order filter and one first order filter, all in low pass, you should be able to obtain a fifth order low pass filter.
 

you can do it with one opamp, look at the burr brown operational amplifier handbook, should be in your universities library, also try doing your own homework instead of asking other people for help. Or if this is a real problem, dont use a 741, it has a capacitor to force it to be dominant pole stable which causes ridiculous slew, resulting in bad time domain response, a better cheap alt is a LF411
