Internal microcontroller ADC What you should know about internal microcontroller ADC. How to choose right reference voltage and power supply. Many microcontrollers contains internal on-chip ADC. Typical devices would be Atmel Atmega series microcontrollers like Atmega8 and further. Internal ADC are successive way to integrate analog world in to your embedded systems using only one microcontroller die. Many applications doesn’t require high speed or high accuracy ADC conversions, thus on-chip ADC is best choice.Lets l avr-microcontrollers in Public bookmarkswith adcatmega8internal_adcon-chipvref
