Layout, Grounding, and Bypassing
For best performance, use PC boards. Do not use wire-
wrap boards. Board layout should ensure that digital
and analog signal lines are separated from each other.
Do not run analog and digital (especially clock) signals
parallel to one another or run digital lines underneath
the ADC package.
High-frequency noise in the V
DD
power supply may
affect ADC performance. Bypass the supply with a
0.1礔 capacitor close to pin V
DD
. Minimize capacitor
lead lengths for best supply-noise rejection. If the
power supply is very noisy, connect a 10& resistor in
series with the supply to provide lowpass filtering.
Definitions
Relative Accuracy
Relative accuracy 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 lin-
earity parameters for the MAX1298/MAX1299 are mea-
sured using the best-straight-line-fit method.
Differential Nonlinearity (DNL)
Differential nonlinearity 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.
Offset Error
The offset error is the difference between the ideal and
the actual offset points. For an ADC, the offset point is
the midstep value when the digital output is zero.
Gain Error
The gain or full-scale error is the difference between
the ideal and actual gain points on the transfer function,
after the offset error has been canceled out. For an
ADC, the gain point is the midstep value when the digi-
tal output is full scale.
Aperture Delay
Aperture delay (t
AD
) is the time defined between the
rising edge of the sampling clock and the instant when
an actual sample is taken.
