supply by connecting them with a low value (10Ω)
resistor or ferrite bead.
The ADC is sensitive to high-frequency noise on the
AV
capacitor in parallel with a 1µF to 10µF low-ESR capacitor
with the smallest capacitor closest to the device. Keep
capacitor leads short to minimize stray inductance.
Integral nonlinearity (INL) 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 endpoints of the transfer function,
once offset and gain errors have been nullified. The
static linearity parameters for the MAX1156/MAX1158/
MAX1174 are measured using the endpoint method.
Differential nonlinearity (DNL) is the difference between
an actual step-width and the ideal value of 1LSB. A
DNL error specification of 1LSB guarantees no missing
codes and a monotonic transfer function.
