ADC Calculator: Analog to Digital Converter

adc analog digital converter digital signal analog signal conversion

This n-bit ADC calculator helps you convert an analog input signal into a digital output. It uses the ADC conversion formula to perform the calculation.

ADC Conversion Caluclator and Example

Inputs

Outputs

The Analog to Digital Converter calculator relies on a specific formula. Let’s look at some examples to see how it works:

EXAMPLE #1:

  • Inputs:
    • n (number of bits) = 3
    • Analog input (V_in) = 5.5V
    • Reference voltage (V_ref) = 8 V
  • Output:
    • 5 (numeric/decimal)
    • 101 (binary)

EXAMPLE #2:

  • Inputs:
    • n (number of bits) = 10
    • Analog input (V_in) = 0.806V
    • Reference voltage (V_ref) = 3.3 V
  • Output:
    • 250 (numeric/decimal)
    • 1111 1010 (binary)
