Make this connection with a low-value, surface-mount
resistor (1 to 5), a ferrite bead, or a direct short.
Alternatively, all ground pins could share the same
ground plane, if the ground plane is sufficiently isolated
from any noisy digital system’s ground plane (e.g.,
downstream output buffer or DSP ground plane).
Route high-speed digital signal traces away from sensi-
tive analog traces. Make sure to isolate the analog
input lines to each respective converter to minimize
channel-to-channel crosstalk. Keep all signal lines short
and free of 90° turns.
Dynamic Parameter Definitions
ADC and DAC Static Parameter Definitions
Integral Nonlinearity (INL)
Integral nonlinearity is the deviation of the values on an
actual transfer function from a straight line. This straight
line can be either a best-straight-line fit or a line drawn
between the end points of the transfer function, once
offset and gain errors have been nullified. The static lin-
earity parameters for the device are measured using
the best straight line fit (DAC Figure 13a).
Differential Nonlinearity (DNL)
Differential nonlinearity is the difference between an
actual step width and the ideal value of 1 LSB. A DNL
error specification of less than 1 LSB guarantees no
missing codes (ADC) and a monotonic transfer function
(ADC and DAC) (DAC Figure 13b).
ADC Offset Error
Ideally, the midscale transition occurs at 0.5 LSB above
midscale. The offset error is the amount of deviation
between the measured transition point and the ideal
transition point.
DAC Offset Error
Offset error (Figure 13a) is the difference between the
ideal and actual offset point. The offset point is the out-
put value when the digital input is midscale. This error
affects all codes by the same amount and usually can
be compensated by trimming.
