AD586
PRECISION CURRENT SOURCE
The design of the AD586 allows it to be easily configured as a
current source. By choosing the control resistor RC in Figure 15,
you can vary the load current from the quiescent current (2 mA
typically) to approximately 10 mA. The compliance voltage of
this circuit varies from about +5 V to +21 V depending upon
the value of VIN.
PRECISION HIGH CURRENT SUPPLY
For higher currents, the AD586 can easily be connected to a
power PNP or power Darlington PNP device. The circuit in
Figure 16 can deliver up to 4 amps to the load. 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.
