Using Fixed Voltage Reference (FVR) for A/D conversion in enhanced mid-range PIC microcontrollers
The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the […]
