Channel select bits. Four bits select which analog input channels are to be used for conversion
(Tables 3 and 4). Defaulted to 0000 at power-up. For MAX1136/MAX1137, CS3 and CS2 are
internally set to 0.
0SGL/
DIF
1 = single-ended, 0 = differential (Tables 3 and 4). Defaulted to 1 at power-up. See the Single-
Ended/Differential Input section.

1. For MAX1136/MAX1137, CS3 and CS2 are internally set to 0.
2. When SEL1 = 1, a single-ended read of AIN3/REF (MAX1136/MAX1137) or AIN11/REF (MAX1138/MAX1139) will be ignored; scan
will stop at AIN2 or AIN10.
