APPLICATIONS INFORMATION
Multiplexer (MUX) Address
The bits of the input word following the START bit assign
the MUX conguration 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 followintg tables.
In single-ended mode, all input channels are measured
with respect to GND.
MSB-First/LSB-First (MSBF)
The output data of the LTC1098(L) is programmed for
MSB-rst or LSB-rst sequence using the MSBF bit.
When the MSBF bit is a logical one, data will appear on
the DOUT line in MSB-rst format. Logical zeros will be
lled in indenitely following the last data bit. When the
MSBF bit is a logical zero, LSB-rst data will follow the
normal MSB-rst data on the DOUT line. (see Operating
Sequence)

Unipolar Transfer Curve
The LTC1096(L)/LTC1098(L) are permanently congured
for unipolar only. The input span and code assignment for
this conversion type are shown in the following gures
for a 5V reference.

Operation with DIN and DOUT Tied Together
The LTC1098(L) can be operated with DIN and DOUT tied
together. This eliminates one of the lines required to com-
municate to the microprocessor (MPU). Data is transmit-
ted in both directions on a single wire. The processor pin
connected to this data line should be congurable as either
an input or an output. The LTC1098(L) will take control of
