GENERAL DESCRIPTION
The AD584 is an eight-terminal precision voltage reference offering pin-programmable selection of four popular output voltages: 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-programmable output levels and temperature coefficients, resulting
in the most flexible high precision voltage reference available in
monolithic form.
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, lowpower 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.
The AD584 is recommended for use as a reference for 8-, 10- or
12-bit D/A converters which require an external precision reference. The device is also ideal for all types of A/D converters of
up to 14-bit accuracy, either successive approximation or integrating designs, and in general can offer better performance
than that provided by standard self-contained references.
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.

PRODUCT HIGHLIGHTS
1. The flexibility of the AD584 eliminates the need to designin and inventory several different voltage references. Furthermore one AD584 can serve as several references
simultaneously when buffered properly.
2. Laser trimming of both initial accuracy and temperature coefficient results in very low errors over temperature without
the use of external components. The AD584LH has a maximum 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” configuration as a negative reference.
4. The output of the AD584 is configured to sink or source
currents. This means that small reverse currents can be tolerated 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).
5. The AD584 is available in versions compliant with MILSTD-883. Refer to the Analog Devices Military Products
Databook or current AD584/883B data sheet for detailed
specifications.
