I'm trying to measure a fork's lift battery by an ADC. The problem that the output voltage isn't predictable and not constant, so that I can make a constant voltag divider. What I have measure is it goes from 7 to 30VDC, and the max input voltage of my adc is 1.2V. How would I design the voltage dividers and the op-amps in that case?
