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 DIN input which configures the LTC1090
for the next conversion. Simultaneously, the result of the
previous conversion is output on the DOUT line. At the end
of the data exchange the requested conversion begins and
CS should be brought high. After tCONV, 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 DIN
input on the first eight rising SCLK edges after chip select
is recognized. Further inputs on the DIN 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.
