Regarding opamps
Hi all,
i've been looking for a circuit may be based on OP AMP solution.
My requirement is that i am feeding varying input voltage (0 to 24V) to an circuit (could be op amp) it's output would be 0 to 3.3V.
So thing is my output should be correlated with input that means
1. Say input is 0% (0V) my output shout be 0% (0V).
2. Say input is 50% (12V) output should be 50% (1.65V)
3. Say input is 100% (24V) output should be 100% (3.3V)
Do anyone have idea on how to have circuit for this.
Thanks,
-Santhakumar.

Wagner LipnharskiSanthakumar, okay, I will grab this fish. Use resistor divider, 3k3 Ohms in parallel with the measured output and a 20k7 (18k + 2k7) Ohms in series with the input. The value of the resistors may change, based on the impedance of the circuit connected to this output. -
Santhakumar AHi Wagner..
thanks,
it works well..
