This tool calculates the digital output of an analog-to-digital converter (ADC).
Formula
Digital output = 2n * (Analog input voltage)/(Analog reference voltage)
Example
Consider a 10 bit ADC. The reference voltage is 5 Volt and the input voltage is 1 Volt. The digital output is 205. The binary equivalent of this number output from the ADC is 11001101.
