MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -An ADC generates a digital output that’s proportional to the ratio of the input voltage to the input range. The resolution ( or least significant bit) is this range divided by the total number of possible steps. For example, an 8-bit ADC with a 2.048-V input range has a resolution of 8 mV (2.048 V/28 steps).

Detailed explanation-2: -ADC0804 is an IC(integrated circuit) which converts the input analog voltage to its equivalent digital output. It is a stand alone analog to digital converter.
