AD5304/AD5314/AD5324  
Data Sheet  
APPLICATIONS INFORMATION  
Bipolar Operation Using the AD5304/AD5314/AD5324  
TYPICAL APPLICATION CIRCUIT  
The AD5304/AD5314/AD5324 have been designed for single  
supply operation, but a bipolar output range is also possible  
using the circuit in Figure 41. 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.  
R2 = 10kΩ  
The AD5304/AD5314/AD5324 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 would be the AD589, a 1.23 V band  
gap reference. Figure 40 shows a typical setup for the AD5304/  
AD5314/AD5324 when using an external reference.

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 is not very  
accurate and can be noisy, the AD5304/AD5314/AD5324 can  
be powered from the reference voltage; for example, using a 5 V  
reference such as the REF195. The REF195 can output a steady  
supply voltage for the AD5304/AD5314/AD5324. The current  
required from the REF195 is 600 ꢁA supply current and approxi-  
mately 112 ꢁA 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:  
REFIN = 5 V, R1 = R2 = 10 kΩ  
V
OUT = (10 × D/2N) − 5 V  
712 ꢁA + 4 (5 V/10 kΩ) = 2.70 mA  
The load regulation of the REF195 is typically 2 ppm/mA, resulting  
in an error of 5.4 ppm (27 ꢁV) 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.
