BIT
NAME
DESCRIPTION
7 (MSB)
START
Start bit. The first logic 1 bit after CS goes low defines the beginning of the control byte.
6
SEL2
5
SEL1
4
SEL0
Channel-select bits. The channel-select bits select which of the eight channels are used for the conversion
(Tables 2, 3, 4, and 5).
3
SGL/DIF
1 = single ended, 0 = differential. Selects single-ended or differential conversions. In single-ended mode,
input signal voltages are referred to COM. In differential mode, the voltage difference between two channels
is measured.
2
UNI/BIP
1 = unipolar, 0 = bipolar. Selects unipolar or bipolar conversion mode. In unipolar mode, connect COM to
AGND to perform conversion from 0 to VREF. In bipolar mode, connect COM to VREF/2 to perform conversion
from 0 to VREF. See Table 7.
1
PD1
0 (LSB)
PD0
Selects clock and power-down modes.
PD1 = 0 and PD0 = 0 selects full power-down mode*.
PD1 = 0 and PD0 = 1 selects fast power-down mode*.
PD1 = 1 and PD0 = 0 selects internal clock mode.
PD1 = 1 and PD0 = 1 selects external clock mode.
