Applications Information
Noise Reduction
Additional samples can be taken and averaged (over-
sampling) to remove the effect of transition noise on
conversion results. The square root of the number of
samples determines the improvement in performance.
For example, with 2/3 LSBRMS (4 LSBP-P) transition
noise, 16 (42 = 16) samples must be taken to reduce
the noise to 1 LSBP-P.
Interface with 4–20mA Signals
Figure 18 illustrates a simple interface between the
MAX1303 and a 4–20mA signal. 4–20mA signaling can
be used as a binary switch (4mA represents a logic-low
signal, 20mA represents a logic-high signal), or for pre-
cision communication where currents between 4mA
and 20mA represent intermediate analog data. For
binary switch applications, connect the 4–20mA signal
to the MAX1303 with a resistor to ground. For example,
a 200
resistor converts the 4–20mA signal to a 0.8V to
4V signal. Adjust the resistor value so the parallel com-
bination of the resistor and the MAX1303 source
impedance is 200
. In this application, select the sin-
gle-ended 0V to VREF range (R[2:0] = 011, Table 6).
For applications that require precision measurements
of continuous analog currents between 4mA and 20mA,
use a buffer to prevent the MAX1303 input from divert-
ing current from the 4–20mA signal.
