In my project i am utlising 3 ADC channels and to display on an LCD. All the ADC's are working properly but independently. But all together, i am facing some issues.
Assume the first ADC output is 12v and second ADC output is 0v. the o/p is perfect. but the first ADC output is 0 and second ADC is 12. the LCD is displaying a value less than 12 volts, but when i increase the first adc input voltage my second adc o/p is getting corrected.
what might be the reason?
