Definition of Terms
Nonlinearity: Error contributed by deviation of the DAC
transfer function from a “best straight line” through the actual
plot of transfer function. Normally expressed as a
percentage of full scale range or in (sub)multiples of 1 LSB.
Resolution: It is addressing the smallest distinct analog
output change that a D/A converter can produce. It is
commonly expressed as the number of converter bits. A
converter with resolution of n bits can resolve output changes
of 2
conversion. Resolution by no means implies linearity.
Settling Time: Time required for the output of a DAC to
settle to within specified error band around its final value
(e.g.,
inputs LOW to HIGH and HIGH to LOW.
Gain Error: The difference between actual and ideal analog
output values at full-scale range, i.e., all digital inputs at
HIGH state. It is expressed as a percentage of full scale
range or in (sub)multiples of 1 LSB.
