Differential Common-Mode Range
The MAX1300/MAX1301 differential common-mode
range (VCMDR) must remain within -14V to +10V to obtain
valid conversion results. The differential common-mode
range is defined as:
(CH_+) + (CH_−)
VCMDR =
2
In addition to the common-mode input voltage limitations,
each individual analog input must be limited to ±16.5V
with respect to AGND1.
The range-select bits R[2:0] in the analog input config-
uration bytes determine the full-scale range for the cor-
responding channel (Tables 2 and 6). Figures 9, 10,
and 11 show the valid analog input voltage ranges for
the MAX1300/MAX1301 when operating with FSR =
(±3 x VREF)/2, FSR = ±3 x VREF, and FSR = ±6 x VREF,
respectively. The shaded area contains the valid com-
mon-mode voltage ranges that support the entire FSR.
