This tool calculates the digital output of an analog-to-digital converter (ADC).

## Formula

**Digital output = 2 ^{n} * (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.

**Related Calculators**

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.
