The AD586 can also be used as a precision reference for multi-
ple DACs. Figure 21 shows the AD586, the AD7628 dual DAC,
and the AD712 dual op amp hooked up for single-supply opera-
tion to produce 0 V to ?5 V outputs. Because both DACs are on
the same die and share a common reference and output op
amps, the DAC outputs will exhibit similar gain TCs.
PRECISION CURRENT SOURCE
The design of the AD586 allows it to be easily configured as a
the user can vary the load current from the quiescent current
(typically, 2 mA) to approximately 10 mA. The compliance volt-
age of this circuit varies from about 5 V to 21 V, depending on
the value of V IN .

STACKED PRECISION REFERENCES FOR
MULTIPLE VOLTAGES
Often, a design requires several reference voltages. Three
AD586s can be stacked, as shown in Figure 22, to produce
For higher currents, the AD586 can easily be connected to a
power PNP or power Darlington PNP device. The circuit in
The 0.1 μF capacitor is required only if the load has a significant
capacitive component. If the load is purely resistive, improved
high frequency supply rejection results can be obtained by
removing the capacitor.
5.000 V, 10.000 V, and 15.000 V outputs. This scheme can be
extended to any number of AD586s, provided the maximum
load current is not exceeded. This design provides the addi-
tional advantage of improved line regulation on the 5.0 V
output. Changes in V IN of 18 V to 50 V produce output changes
that are below the noise level of the references.
