DESCRIPTION
Register bit 1 = setup byte (see Table 1), 0 = configuration byte.
Scan select bits. Two bits select the scanning configuration (Table 5). Default to 00 at power-up.
Channel select bits. Four bits select which analog input channels are to be used for conversion
(Tables 3 and 4). Default to 0000 at power-up. For MAX1236/MAX1237, CS3 and CS2 are
internally set to 0.
0
SGL/
DIF
1 = single-ended, 0 = differential (Tables 3 and 4). Default to 1 at power-up. See the
Single-
Ended/Differential Input
section.

1. For MAX1236/MAX1237, CS3 and CS2 are internally set to 0.
2. When SEL1 = 1, a single-ended read of AIN3/REF (MAX1236/MAX1237) or AIN11/REF (MAX1238/MAX1239) is ignored; scan
stops at AIN2 or AIN10.
