Hello guys i have to measure a voltage using ADC and display it on LCD display or seven segment display. My problem is that the the voltage to be measured is from 0-70 volts. if i use a 2.5 voltage reference, and use voltage divider, i think it will not be accurate anymore because of resistor tolerance. any better idea on how? regards mago
