AD581

the initial tolerance is 10 mV, the temperature error band is

15 mV, thus the unit is guaranteed to be 10.000 volts 25 mV

from –55°C to +125°C).

OUTPUT CURRENT CHARACTERISTICS

The AD581 has the capability to either source or sink current

and provide good load regulation in either direction, although it

has better characteristics in the source mode (positive current

into the load). The circuit is protected for shorts to either posi-

tive supply or ground. The output voltage vs. output current

characteristics of the device are shown in Figure 5. Source cur-

rent is displayed as negative current in the figure; sink current is

positive. Note that the short circuit current (i.e., zero volts out-

put) is about 28 mA; when shorted to +15 volts, the sink cur-

rent goes to about 20 mA.

PRECISION HIGH CURRENT SUPPLY

The AD581 can be easily connected with power pnp or power

Darlington pnp devices to provide much greater output current

capability. The circuit shown in Figure 9 delivers a precision

10 volt output with up to 4 amperes supplied 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 from removing the

capacitor.

DYNAMIC PERFORMANCE

Many low power instrument manufacturers are becoming in-

creasingly concerned with the turn-on characteristics of the

components being used in their systems. Fast turn-on compo-

nents often enable the end user to keep power off when not

needed, and yet respond quickly when the power is turned on

for operation. Figure 6 displays the turn-on characteristic of

the AD581. This characteristic is generated from cold-start

operation and represents the true turn-on waveform after an

extended period with the supplies off. The figure shows both the

coarse and fine transient characteristics of the device; the total

settling time to within 10 millivolt is about 180 µs, and there is

no long thermal tail appearing after the point.
