Voltage Resolution (Analog to Digital)

Voltage resolution, Analog to Digital Converters (ADC) is the smallest change in voltage that the ADC can detect or represent in its digital output.  It is determined by the number of bits used by the ADC and the range of input voltage it can measure.

 

Voltage Resolution (Analog to Digital) formula
\( V_r \;=\;  V_h - V_l \;/\; 2^n  \)     (Voltage Resolution) \( V_h \;=\;  V_r \; 2^n + V_l \) \( V_l \;=\;  V_h - V_r \; 2^n  \)
Symbol	English	Metric
\( V_r \) =  Voltage Resolution	-	\(V\)
\( V_h \) = High Voltage	-	\(V\)
\( V_l \) = Low Voltage	-	\(V\)
\( n \) = Conversion Bits (4, 8, 10, 12, 16, etc.)	-	\(dimensionless\)
