M
example, the Belden 8451 works well for distances up
to 100 feet in a noisy environment. Connect the shield
to SH0-0H.
Cable resistances affect remote-sensor accuracy; 1
series resistance introduces +0.45
°
C error.
Remote Diode Shielding
Temperature measurements will reflect significant error
if a portion of the bias current supplied to the diode
anode is allowed to flow through parallel paths to
ground. If the diode-connected transistor is mounted
on a PC board, suppress error-producing

current by surrounding the collector/base leads with a
metal trace that is connected to the SHO shield output
(Figure 8).
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
0.1μF 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 MAX1098/MAX1099 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
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
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.
