The first “l(fā)ogical one” clocked into the D
IN
input after CS
goes low is the start bit. The start bit initiates the data
transfer. The LTC1091/LTC1093/LTC1094 will ignore all
leading zeros which precede this logical one. After the start
bit is received, the remaining bits of the input word will be
clocked in. Further inputs on the D
IN
pin are then ignored
until the next CS cycle.
Multiplexer (MUX) Address
The bits of the input word following the START bit assign
the MUX configuration for the requested conversion. For
a given channel selection, the converter will measure the
voltage between the two channels indicated by the + and
– signs in the selected row of the following tables. In
single-ended mode, all input channels are measured with
respect to GND on the LTC1091 and COM on the
LTC1093/LTC1094.
