n bit ADC calculator, Analog Input Digital Output

This page mentions n-bit ADC calculator. The ADC calculator takes analog input and provides digital output. The ADC conversion formula/equations are also mentioned.

Number of bits (n) in ADC (Input-1)   :

Analog Voltage input to ADC (Input-2)   :

Reference voltage to ADC (Input-3)   :

Numeric Digital Output (output-1) :

Binary Digital Output (output-2) :


*Note: Enter values in INPUT boxes and Press CALCULATE button to check OUTPUTS.

EXAMPLE#1:
INPUTS: n = 3, Analog input (V_in) = 5.5V, Ref_voltage (V_ref) = 8 V
OUTPUT: 5.5 numeric (decimal), 101 (binary)

EXAMPLE#2:
INPUTS: n = 10, Analog input (V_in) = 0.806V, Ref_voltage (V_ref) = 3.3 V
OUTPUT: 250 numeric (decimal), 1111 1010 (binary)
