AD5305/AD5315/AD5325  
If an output range of 0 V to VDD is required, the simplest solution  
is to connect the reference input to VDD. As this supply may not be  
very accurate and may be noisy, the AD5305/AD5315/AD5325  
may be powered from the reference voltage; for example, using  
a 5 V reference such as the REF195. The REF195 will output  
a steady supply voltage for the AD5305/AD5315/AD5325. The  
typical current required from the REF195 is 600 µA supply cur-  
rent and approximately 112 µA into the reference input. This is  
with no load on the DAC outputs. When the DAC outputs are  
loaded, the REF195 also needs to supply the current to the loads.  
The total current required (with a 10 kΩ load on each output) is  
Multiple Devices on One Bus  
Figure 13 shows two AD5305 devices on the same serial bus.  
Each has a different slave address since the state of the A0 pin is  
different. This allows each of eight DACs to be written to or  
read from independently.

The load regulation of the REF195 is typically 2 ppm/mA, which  
results in an error of 5.4 ppm (27 µV) for the 2.7 mA current  
drawn from it. This corresponds to a 0.0014 LSB error at eight  
bits and 0.022 LSB error at 12 bits.

Bipolar Operation Using the AD5305/AD5315/AD5325  
AD5305/AD5315/AD5325 as a Digitally Programmable Window  
Detector  
The AD5305/AD5315/AD5325 have been designed for single-  
supply operation, but a bipolar output range is also possible using  
the circuit in Figure 12. This circuit will give an output voltage  
range of 5 V. Rail-to-rail operation at the amplifier output is  
achievable using an AD820 or an OP295 as the output amplifier.  
A digitally programmable upper/lower limit detector using two  
of the DACs in the AD5305/AD5315/AD5325 is shown in  
Figure 14. The upper and lower limits for the test are loaded to  
DACs A and 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 will indicate the fail condition. Similarly, DACs C and  
D can be used for window detection on a second VIN signal.

The output voltage for any input code can be calculated as  
follows:  
Coarse and Fine Adjustment Using the AD5305/AD5315/  
AD5325  
N
Two of the DACs in the AD5305/AD5315/AD5325 can be  
paired together to form a coarse and fine adjustment function,  
as shown in Figure 15. DAC A is used to provide the coarse  
adjustment while DAC B provides the fine adjustment. Varying  
the ratio of R1 and R2 will change the relative effect of the  
coarse and fine adjustments. With the resistor values and exter-  
nal reference shown, the output amplifier has unity gain for the  
DAC A output, so the output range is 0 V to 2.5 V – 1 LSB. For  
DAC B, the amplifier has a gain of 7.6 × 10–3, giving DAC B  
a range equal to 19 mV. Similarly, DACs C and D can be paired  
together for coarse and fine adjustment.

ages up to VDD may be used. The op amps indicated will allow
