GENERAL DESCRIPTION

The AD584 is an eight-terminal precision voltage reference of-

fering pin-programmable selection of four popular output volt-

ages: 10.000 V, 7.500 V, 5.000 V and 2.500 V. Other output

voltages, above, below or between the four standard outputs, are

available by the addition of external resistors. Input voltage may

vary between 4.5 and 30 volts.

Laser Wafer Trimming (LWT) is used to adjust the pin-pro-

grammable output levels and temperature coefficients, resulting

in the most flexible high precision voltage reference available in

monolithic form.

PRODUCT HIGHLIGHTS

1. The flexibility of the AD584 eliminates the need to design-

in and inventory several different voltage references. Fur-

thermore one AD584 can serve as several references

simultaneously when buffered properly.

In addition to the programmable output voltages, the AD584

offers a unique strobe terminal which permits the device to be

turned on or off. When the AD584 is used as a power supply

reference, the supply can be switched off with a single, low-

power signal. In the “off” state the current drain by the AD584

is reduced to about 100 µA. In the “on” state the total supply

current is typically 750 µA including the output buffer amplifier.

2. Laser trimming of both initial accuracy and temperature co-

efficient results in very low errors over temperature without

the use of external components. The AD584LH has a maxi-

mum deviation from 10.000 volts of ±7.25 mV from 0°C to

+70°C.

3. The AD584 can be operated in a two-terminal “Zener”

mode at 5 volts output and above. By connecting the input

and the output, the AD584 can be used in this “Zener” con-

figuration as a negative reference.

The AD584 is recommended for use as a reference for 8-, 10- or

12-bit D/A converters which require an external precision refer-

ence. The device is also ideal for all types of A/D converters of

up to 14-bit accuracy, either successive approximation or inte-

grating designs, and in general can offer better performance

than that provided by standard self-contained references.

4. The output of the AD584 is configured to sink or source

currents. This means that small reverse currents can be tol-

erated in circuits using the AD584 without damage to the

reference and without disturbing the output voltage (10 V,

7.5 V and 5 V outputs).

The AD584J, K and L are specified for operation from 0°C to

+70°C; the AD584S and T are specified for the –55°C to

+125°C range. All grades are packaged in a hermetically sealed

eight-terminal TO-99 metal can; the AD584 J and K are also

available in an 8-pin plastic DIP.

5. The AD584 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Databook or current AD584/883B data sheet for detailed

specifications.
