Data Sheet  
AD5381  
AD5381  
Figure 44 shows a typical configuration when using the internal  
reference. On power-up, the AD5381 defaults to an external  
reference; therefore, the internal reference needs to be config-  
ured and turned on via a write to the AD5381 control register.  
Control Register Bit CR10 allows the user to choose the  
reference value; Bit CR8 is used to select the internal reference.  
It is recommended to use the 2.5 V reference when AVDD =  
5 V, and the 1.25 V reference when AVDD= 3 V.

TYPICAL CONFIGURATION CIRCUIT  
Figure 43 shows a typical configuration for the AD5381-5  
when configured for use with an external reference. In the  
circuit shown, all AGND, SIGNAL_GND, and DAC_GND pins  
are tied together to a common AGND. AGND and DGND are  
connected together at the AD5381 device. On power-up, the  
AD5381 defaults to external reference operation. All AVDD  
lines are connected together and driven from the same 5 V  
source. It is recommended to decouple close to the device with a  
0.1 µF ceramic and a 10 µF tantalum capacitor. In this application,  
the reference for the AD5381-5 is provided externally from  
either an ADR421 or ADR431 2.5 V reference. Suitable external  
references for the AD5381-3 include the ADR3412 1.2 V  
reference. The reference should be decoupled at the  
Figure 44. Typical Configuration with Internal Reference  
Digital connections have been omitted for clarity. The AD5381  
contains an internal power-on reset circuit with a 10 ms brown-  
out time. If the power supply ramp rate exceeds 10 ms, the user  
should reset the AD5381 as part of the initialization process to  
ensure the calibration data is loaded correctly into the device.
