Hi all,
I have a sensor which outputs 13mV per degree. It will be useing it to monitor a full 360 degrees. How can I set the the PIC18F ADC reference voltsge to get 13mV resoultion?
My first step is to set the ADC in 10-bit mode since I cannot get 360 degrees from an 8-bit ADC.
Multiplying 13mV by 1024 will 13.3V which exceeds the 5V limit.
Dividing 13mV by 2 to set two bits for every degrees also gets above the 5V limit ( 13mV/2 = 6.5mV .... 6.5mV * 1024 = 6.7V)
Is there a way to achieve this without reducing the sensor output voltage please?
