GALVANICALLY ISOLATED INTERFACE
In many process control applications, it is necessary to provide
an isolation barrier between the controller and the unit being
controlled to protect and isolate the controlling circuitry from
any hazardous common-mode voltages that may occur. The
iCoupler® family of products from Analog Devices, Inc., provides
voltage isolation in excess of 5.0 kV. The serial loading structure
of the AD5748 makes it ideal for isolated interfaces because the
number of interface lines is kept to a minimum. Figure 56 shows
a 4-channel isolated interface using an ADuM1400. For further

MICROPROCESSOR INTERFACING
Microprocessor interfacing to the AD5748 is via a serial bus
that uses a protocol compatible with microcontrollers and DSP
processors. The communications channel is a 3-wire (minimum)
interface consisting of a clock signal, a data signal, and a SYNC
signal. The AD5748 requires a 16-bit data-word with data valid
on the falling edge of SCLK.
