Chain Mode, Multiple Devices
When CHAIN = OVDD, the LTC2376-18 operates in chain
mode. In chain mode, SDO is always enabled and RDL/SDI
serves as the serial data input pin (SDI) where daisy-chain
data output from another ADC can be input.
This is useful for applications where hardware constraints
may limit the number of lines needed to interface to a large
number of converters. Figure 15 shows an example with
two daisy-chained devices. The MSB of converter A will
appear at SDO of converter B after 18 SCK cycles. The
MSB of converter A is clocked in at the SDI/RDL pin of
converter B on the rising edge of the first SCK.
