Hi.
I have an analog input DC-signal from 0-45V that I want to measure. But I am onlu interested in measuring between approx. 33V to 45V, as I really don't care if the signal goes below 33V. The interval between 33v - 45V I then wan't to scale to 0-5V so it can be read by my Arduino ADC port.
My first approach was to design some kind of op-amp level shifter, but I really can't get it right. Anyone here that can help me with some pointers or suggestions on how to do this!?
Thanks in advance,
G.F
