Description
7(MSB)
START
The first logic “1” bit after CS goes low defines the beginning of the control byte.
6
SEL2
These three bits select which of the eight channels are used for the conversion.

SEL1
See Tables 1 and 2.

SEL0
3
UNI/BIP
1 = unipolar, 0 = bipolar. Selects unipolar or bipolar conversion mode. In unipolar
mode, an analog input signal from 0V to VREF can be converted; in differential bipolar
mode, the differential signal can range from -VREF / 2 to +VREF / 2. Select differential
operation if bipolar mode is used.
2
SGL/DIF
1 = single ended, 0 = differential. Selects single-ended or differential conversions. In
single-ended mode, input signal voltages are referred to AGND. In differential mode,
the voltage difference between two channels is measured. Select unipolar operation
if single-ended mode is used. See Tables 1 and 2.
