This tool calculates the digital output of an analog-to-digital converter (ADC).
Digital output = 2n * (Analog input voltage)/(Analog reference voltage)
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.
Use the following calculators to find the
- Analog resolution of an ADC
- Signal-to-Noise Ratio of an ADC
Both depend on the number of bits.
