sorry sir for being vague..
I need to sense battery voltage which will be 32V-42V.It has to be scaled to 0-10V.Voltage sense circuit should be using opamp.
the link posted fist **broken link removed** was very useful and it did the function very well.But then my guide doesnto want this circuit,.he suggested try sensing the voltage across the battery using a diff opamp, then may b scale it in next stage of opamp(which would b a non-inverting stage).
i hope i made my problem clear, please help me out.
