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
reference and associated buffers. This leads to an overall savings
in both cost and board space.
In Figure 36, AVDD is connected to +15 V and AVSS is connected
to 15 V. However, AVDD can operate with supplies from +11.4 V
to +16.5 V and AVSS can operate with supplies from 11.4 V to
16.5 V.
