Data Sheet  
APPLICATIONS  
CHOOSING A REFERENCE AS POWER SUPPLY FOR  
THE AD5601/AD5611/AD5621  
BIPOLAR OPERATION USING THE  
AD5601/AD5611/AD5621  
The AD5601/AD5611/AD5621 come in tiny LFCSP and SC70  
packages with less than a 100 µA supply current. Because of  
this, the choice of reference depends on the application  
requirements. For applications with space-saving requirements,  
the ADR02 is recommended. It is available in an SC70 package  
and has excellent drift at 9 ppm/°C (3 ppm/°C in the R-8 package)  
and provides very good noise performance at 3.4 µV p-p in the 0.1  
Hz to 10 Hz range.  
The AD5601/AD5611/AD5621 have been designed for single-  
supply operation, but a bipolar output range is also possible  
using the circuit shown in Figure 52. The circuit in Figure 52  
gives an output voltage range of 5 V. Rail-to-rail operation at  
the amplifier output is achievable using an AD820 or OP295 as  
the output amplifier.  
R2 = 10kΩ  
+5V  
+5V  
R1 = 10kΩ  
Because the supply current required by the AD5601/AD5611/  
AD5621 is extremely low, the parts are ideal for low supply  
applications. The ADR395 voltage reference is recommended in  
this case. It requires less than 100 µA of quiescent current and  
can, therefore, drive multiple DACs in one system, if required. It  
also provides very good noise performance at 8 µV p-p in the  
0.1 Hz to 10 Hz range.
