Y = mv2adc(X, voltageRange, maxValue)

Description

mv2adc(X, voltageRange, maxValue) returns an Analogue to Digital Converter count value corresponding for the input value X scaled according to the voltage range specified.

Example

X = [-500, -250, 0, 250, 500];
voltageRange = 1000; % ±1 V range
maxValue = 32512;

Y = mv2adc(X, voltageRange, maxValue)

Y =

  1×5 int32 row vector

   -16256    -8128        0     8128    16256

Input Arguments

X - the raw ADC value(s), (scalar, vector or matrix of real, finite with no NaN (Not a Number) elements)
voltageRange - the voltage range used for the channel (positive, non-zero integer scalar value, in millivolts)
maxValue - the maximum ADC value corresponding to the resolution for the device (positive, non-zero integer scalar value)

The units for voltageRange can be changed e.g. volts.

Output Arguments

Y - the converted values (scalar, vector or matrix of 32-bit integers; in millivolts).

Note: If a different unit is used for the input X, then Y will have the corresponding units.
