Normal Mode, Single Device
When CHAIN = 0, the LTC2377-16 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 LTC2377-16 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 LTC2377-16.
