    problem using LM741 operational amplifier

    basically i want 4 different voltages level to be assigned. now the four different levels must be +5, +3, -3, -5. now i am unable tyo do this because the operational amplifier is not working as its layout specifies. please guide me for both inverting and non-inverting behavior.

    Re: problem using LM741 operational amplifier

    Can you explain more clearly what you are trying to do?
    Are you trying to build a voltage follower and switch its input to various voltages?

    Hi,

    I would recommend that you use another op-amp instead, the 741 is no good in this voltage range. The TLC25L2 or the SA5230 would probably work in your application.

    problem using LM741 operational amplifier

    Can you show us a schematic of your circuit and tell us what voltages you expect and what you are measuring?

    Try another 741, maybe you grabbed a dead one.

    Ante, the 741 works fine in this voltage range.
