AD5302/AD5312/AD5322  
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 42 shows a  
diagram of a typical setup for decoding multiple AD5302/  
AD5312/AD5322 devices in a system.  
OPTO-ISOꢀATED INTERFACE FOR PROCESS  
CONTROꢀ APPꢀICATIONS  
Each AD5302/AD5312/AD5322 has a versatile 3-wire serial  
interface, making them ideal for generating accurate voltages in  
process control and industrial applications. Due to noise, safety  
requirements, or distance, it can be necessary to isolate the  
AD5302/AD5312/AD5322 from the controller. This can easily  
be achieved by using opto-isolators, which provide isolation in  
excess of 3 kV. The serial loading structure of the AD5302/  
AD5312/AD5322 makes them ideally suited for use in opto-  
isolated applications. Figure 41 shows an opto-isolated interface

are driven from opto-couplers. The power supply to the part  
also needs to be isolated by using a transformer. On the DAC  
side of the transformer, a 5 V regulator provides the 5 V supply  
required for the AD5302/AD5312/AD5322.

Figure 43 shows a digitally programmable upper-/lower-limit  
detector using the two DACs in the AD5302/AD5312/AD5322.  
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 programmed window,  
an LED indicates the fail condition.
