CONFIG
The configuration byte always starts with 0.

SCAN0
SCAN1, SCAN0 = [0,0], scans from channel 0 to the upper channel chosen by CS1, CS0.
SCAN1, SCAN0 = [0,1], converts a single channel chosen by CS1, CS0 eight times.
SCAN1, SCAN0 = [1,0] monitor mode monitors from channel 0 to the upper channel chosen by CS1, CS0.
SCAN1, SCAN0 = [1,1], single channel conversion for the channel is chosen by CS0, CS1.
4CS3
3CS2
CS3, CS2 = [1,1] enables readback of monitor-mode setup data.
2CS1
1CS0
Selects the upper limit of the channel range used for the conversion sequence in scan modes SCAN = [0,0]
and monitor modes SCAN = [1,0].
Selects the conversion channel when SCAN = [0,1] or when SCAN = [1,1].
(Tables 5 and 6)
0
SE/
DIF
1 = single-ended inputs.
0 = differential inputs.
AIN0 and AIN1 form the first differential pair and AIN2 and AIN3 form the second differential pair. (See Tables
4 and 5.)
Selects single-ended or differential conversions. In single-ended mode, input-signal voltages are referenced
to GND. In differential mode, the voltage difference between two channels is measured.
When single-ended mode is used, the MAX1363/MAX1364 perform unipolar conversions regardless of the
UNI/BIP bit in the setup byte.
