All supplies should be decoupled with large tantalum or
electrolytic capacitors at the point they enter the PCB.
For best performance, bypass all power supplies to the
appropriate ground with a 10μF tantalum capacitor to
filter power-supply noise, in parallel with a 0.1μF
capacitor and a high-quality 47pF ceramic chip capaci-
tor located very close to the MAX108 device to filter
very high-frequency noise.
Static Parameter Definitions
Integral Nonlinearity
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 MAX108 are mea-
sured using the best-straight-line fit method.
Differential Nonlinearity
Differential nonlinearity (DNL) is the difference between
an actual step width and the ideal value of 1LSB. A
DNL error specification of less than 1LSB guarantees
no missing codes and a monotonic transfer function.
