*AFTER COMPLETING THE DATA TRANSFER, IF FURTHER CLOCKS ARE APPLIED WITH CS LOW, THE ADC WILL OUTPUT ZEROS INDEFINITELY.

Input Data Word
The LTC1096(L) requires no DIN word. It is permanently
configured to have a single differential input. The conver-
sion result, in which output on the DOUT line is MSB-first
sequence, followed by LSB sequence providing easy
interface to MSB- or LSB-first serial ports.
The LTC1098(L) clocks data into the DIN input on the ris-
ing edge of the clock. The input data words are defined
as follows:
Start Bit
The first “logical one” clocked into the DIN input after CS
goes low is the start bit. The start bit initiates the data
transfer. The LTC1098(L) 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 DIN pin are then ignored until the
next CS cycle.
