Now, the ramp voltage is compared continuously with the input analog voltage using input comparator.Initially, a ramp voltage is initiated as multivibrator sends a pulse to ramp generator.The block diagram of ramp type ADC is shown in figure1.Microcontrollers commonly use 8, 10, 12, or 16-bit ADCs, our micro controller uses an 8 or 10 bit ADC.įig2.Some examples of ADC usage are digital voltmeters, cell phone, thermocouples, and a digital oscilloscope.
