LTC1090
1090fc
Data transfer is initiated by a falling chip select (CS) signal.
After the falling CS is recognized, an 8-bit input word
is shifted into the D
IN
input which configures the LTC1090
for the next conversion. Simultaneously, the result of the
previous conversion is output on the D
OUT
line. At the end
of the data exchange the requested conversion begins and
CS should be brought high. After t
CONV
, the conversion is
complete and the results will be available on the next data
transfer cycle. As shown below, the result of a conversion
is delayed by one CS cycle from the input word requesting
it.
2. Input Data Word
The LTC1090 8-bit input data word is clocked into the D
IN
input on the first eight rising SCLK edges after chip select
is recognized. Further inputs on the D
IN
pin are then
ignored until the next CS cycle. The eight bits of the input
word are defined as follows:
Multiplexer (MLIX) Address
The first four bits of the input word 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 Table 1. Note that in differential
mode (SGL/DIFF = O) measurements are limited to four
adjacent input pairs with either polarity. In single ended
mode, all input channels are measured with respect to
COM. Figure 1 shows some examples of multiplexer
assignments.
