Table 4. Channel Selection in Pseudo-Differential Mode (SGL /
DIF
= 0)
Note 1:
For MAX1036/MAX1037, CS3 and CS2 are internally set to zero.
Note 2:
When SEL1 =1, a pseudo-differential read between AIN2 and AIN3/REF (MAX1036/MAX1037) or AIN10 and AIN11/REF
(MAX1038/MAX1039) returns the difference between GND and AIN2 or AIN10, respectively. For example, a differential read of
1011 returns the negative difference between AIN10 and GND.
Note 3:
When scanning multiple channels (SCAN0 = 0), CS0 = 0 causes the even-numbered channel-select bits to be scanned,
while CS0 = 1 causes the odd-numbered channel-select bits to be scanned. For example, if the MAX1038/MAX1039
SCAN[1:0] = 00 and CS[3:0] = 1010, a differential read returns AIN0
–
AIN1, AIN2

AIN3, AIN4
–

–

–
AIN9, and AIN10
–
AIN11. If the MAX1038/MAX1039 SCAN[1:0] = 00 and CS[3:0] = 1011, a differential read returns
AIN1
–
AIN0, AIN3
–
AIN2, AIN5
–
AIN4, AIN7
–
AIN6, AIN9
–
8, and AIN11
–
AIN10.
