Many applications require multiple channels of input and output. The
AD743xx series of devices are designed to cater for extending the number
of I/O channels by cascading devices together while interfacing to a single
control or data port. T his reduces the overhead requirement on the
controller in terms of serial ports.
Control Port Cascading
T here are two methods of cascading the Control Ports of
multiple AD743xx devices together so that all devices can
be controlled from a single controller serial port. One
method is to configure the multiple devices as a daisy
chain of Control Ports each 16-bits wide with common
