S/D = SINGLE-ENDED/DIFFERENTIAL BIT
O/S = ODD/SIGN BIT
UNI = UNIPOLAR/BIPOLAR BIT
X = DON’T CARE

Analog Input Multiplexer
The analog input MUX is programmed by the S/D and O/S
bits of the DIN word for the LTC2306 and the O/S bit of the
DIN word for the LTC2302. Table 1 and Table 2 list MUX
congurations for all combinations of the conguration
bits. Figure 1a shows several possible MUX congurations
and Figure 1b shows how the MUX can be recongured
from one conversion to the next.
Driving the Analog Inputs
The analog inputs of the LTC2302/LTC2306 are easy to
drive. Each of the analog inputs of the LTC2306 (CH0
and CH1) can be used as a single-ended input relative
to GND or as a differential pair. The analog inputs of the
LTC2302 (IN+, IN) are always congured as a differential
pair. Regardless of the MUX conguration, the “+” and “–”
inputs are sampled at the same instant. Any unwanted
signal that is common to both inputs will be reduced by
the common mode rejection of the sample-and-hold cir-
cuit. The inputs draw only one small current spike while
