The AD5303/AD5313/AD5323 has a versatile 3-wire serial  
interface making it ideal for generating accurate voltages in  
process control and industrial applications. Due to noise, safety  
requirements, or distance, it may be necessary to isolate the  
AD5303/AD5313/AD5323 from the controller. This can easily  
be achieved by using opto-isolators, which provides isolation  
in excess of 3 kV. The serial loading structure of the AD5303/  
AD5313/AD5323 makes it ideally suited for use in opto-isolated  
applications. Figure 42 shows an opto-isolated interface to the

AD5303/AD5313/AD5323 where DIN, SCLK, and

driven from opto-couplers. The power supply to the part also  
needs to be isolated. This is done by using a transformer. On the  
DAC side of the transformer, a 5 V regulator provides the 5 V  
supply required for the AD5303/AD5313/AD5323.

A digitally programmable upper/lower limit detector using  
the two DACs in the AD5303/AD5313/AD5323 is shown in  
Figure 44. The upper and lower limits for the test are loaded  
to DAC A and DAC B, which, in turn, set the limits on the  
CMP04. If the signal at the VIN input is not within the pro-  
grammed window, an LED indicates the fail condition.

DECODING MULTIPLE AD5303/AD5313/AD5323s  
SYNC  
The  
pin on the AD5303/AD5313/AD5323 can be used  
in applications to decode a number of DACs. In this application,  
all the DACs in the system receive the same serial clock and  
SYNC  
serial data, but only the  
to one of the devices is active at  
any one time, allowing access to two channels in this 8-channel  
system. The 74HC139 is used as a 2-to-4 line decoder to address  
any of the DACs in the system. To prevent timing errors from  
occurring, the enable input should be brought to its inactive  
state while the coded address inputs are changing state.  
Figure 43 shows a diagram of a typical setup for decoding  
multiple AD5303/AD5313/AD5323 devices in a system.
