Route the digital output traces for a high-speed, high-
resolution data converter with care. Keep trace lengths
at a minimum and place minimal capacitive loading,
less than 5pF, on any digital trace to prevent coupling
to sensitive analog sections of the ADC. Run the LVDS
output traces as differential lines with 100Ω characteris-
tic impedance from the ADC to the LVDS load device.
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. However,
the static linearity parameters for the MAX1219 are
measured using the histogram method with a 65MHz
input frequency.
