An ideal linear voltage representation (one without offset or max count adjustments)
is interpreted using the
formula:
where V
n
is the numerical count and V
ai
is the analog input voltage:
However, in systems that require calibration, the formula may actually
be:
(In a perfectly calibrated system, a = 32 000 and b = 0.)
