Timing Diagrams
Normal Mode, Single Device
When CHAIN = 0, the LTC2376-16 operates in normal
mode. In normal mode, RDL/SDI enables or disables the
serial data output pin SDO. If RDL/SDI is high, SDO is in
high impedance. If RDL/SDI is low, SDO is driven.
Figure 13 shows a single LTC2376-16 operated in normal
mode with CHAIN and RDL/SDI tied to ground. With RDL/
SDI grounded, SDO is enabled and the MSB(D15) of the
new conversion data is available at the falling edge of
BUSY. This is the simplest way to operate the LTC2376-16.
