APPLICATIONS INFORMATION
TYPICAL OPERATING CIRCUIT
Figure 36 shows the typical operating circuit for the AD5764.
The only external components needed for this precision 16-bit
DAC are a reference voltage source, decoupling capacitors on
the supply pins and reference inputs, and an optional short-
circuit current setting resistor. Because the device incorporates
reference buffers, it eliminates the need for an external bipolar
