Applications Information
Definitions
Integral Nonlinearity (INL)
Integral nonlinearity (Figure 6a) is the deviation of the val-
ues on an actual transfer function from a straight line.
This straight line can be either a best-straight-line fit
(closest approximation to the actual transfer curve) or a
line drawn between the endpoints of the transfer func-
tion, once offset and gain errors have been nullified. For
a DAC, the deviations are measured at every single step.
Differential Nonlinearity (DNL)
Differential nonlinearity (Figure 6b) is the difference
between an actual step height and the ideal value of
1LSB. If the magnitude of the DNL is less than 1LSB, the
DAC guarantees no missing codes and is monotonic.
Offset Error
The offset error (Figure 6c) is the difference between
the ideal and the actual offset point. For a DAC, the off-
set point is the step value when the digital input is zero.
This error affects all codes by the same amount and
can usually be compensated for by trimming.
Gain Error
Gain error (Figure 6d) is the difference between the
ideal and the actual full-scale output voltage on the
transfer curve, after nullifying the offset error. This error
alters the slope of the transfer function and corre-
sponds to the same percentage error in each step.
Settling Time
The settling time is the amount of time required from the
start of a transition, until the DAC output settles to its new
output value within the converter
’
s specified accuracy.
