AD5306/AD5316/AD5326  
APPLICATIONS  
TYPICAꢀ APPꢀICATION CIRCUIT  
BIPOꢀAR OPERATION USING THE  
AD5306/AD5316/AD5326  
The AD5306/AD5316/AD5326 can be used with a wide range  
of reference voltages where the devices offer full one-quadrant  
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 AD5306/  
AD5316/AD5326 when using an external reference. Note that  
A0 and A1 can be high or low.  
The AD5306/AD5316/AD5326 are 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.

The output voltage for any input code can be calculated as follows:

If an output range of 0 V to VDD is required when the reference  
inputs are configured as unbuffered, the simplest solution is to  
connect the reference inputs to VDD. Because this supply may be  
noisy and somewhat inaccurate, the AD5306/AD5316/AD5326  
may 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 AD5306/AD5316/AD5326. The  
typical current required from the REF195 is 500 μA supply  
current and approximately 112 μA to supply the reference  
inputs, if unbuffered. 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,  
V
OUT = (10 × D/2N) − 5 V  
MUꢀTIPꢀE DEVICES ON ONE BUS  
Figure 38 shows four AD5306 devices on the same serial bus.  
Each has a different slave address since the states of the A0 and  
A1 pins are different. This allows each of 16 DACs to be written  
to or read from independently.  
612 μA + (5 V/10 kΩ) = 2.6 mA

The load regulation of the REF195 is typically 2 ppm/mA,  
which results in an error of 5.2 ppm (26 μV) for the 2.6 mA  
current drawn from it. This corresponds to a 0.0013 LSB error  
at eight bits and a 0.021 LSB error at 12 bits.
