AD5305/AD5315/AD5325  
APPLICATIONS  
TYPICAꢀ APPꢀICATION CIRCUIT  
BIPOꢀAR OPERATION  
The AD5305/AD5315/AD5325 can be used with a wide range  
of reference voltages where the devices offer full, one-quadrant  
The AD5305/AD5315/AD5325 have been designed for single  
supply operation, but a bipolar output range is also possible using  
the circuit in Figure 37. This circuit gives 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.  
multiplying capability over a reference range of 0 V to VDD  
.
More typically, these devices are used with a fixed, precision  
reference voltage. Suitable references for 5 V operation are the  
AD780 and REF192 (2.5 V references). For 2.5 V operation, a  
suitable external reference is the AD589, a 1.23 V band gap  
reference. Figure 36 shows a typical setup for the AD5305/  
AD5315/AD5325 when using an external reference. Note that  
A0 can be high or low.

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 can be powered from the reference  
voltage; for example, using a 5 V reference such as the REF195.  
The REF195 outputs a steady supply voltage for the AD5305/  
AD5315/AD5325. The typical current required from the  
REF195 is 600 μA supply current 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  
where:  
D is the decimal equivalent of the code loaded to the DAC.  
N is the DAC resolution.  
REFIN is the reference voltage input.  
with  
REFIN = 5 V, R1 = R2 = 10 kΩ, VOUT (10 × D/2N) − 5 V  
MUꢀTIPꢀE DEVICES ON ONE BUS  
Figure 38 shows two AD5305 devices on the same serial bus.  
Each has a different slave address because the state of the A0 pin  
is different. This allows each of eight DACs to be written to or  
read from independently.  
712 μA + 4(5 V/10 kΩ) = 2.70 mA  
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.
