GENERAL DESCRIPTION
The AD584 is an 8-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. The input voltage can vary
between 4.5 V and 30 V.
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 that 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 drained by the AD584 is reduced
to approximately 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 digital-to-analog converters (DACs) that require an
external precision reference. In addition, the device is ideal for
analog-to-digital converters (ADCs) of up to 14-bit accuracy,
either successive approximation or integrating designs, and in
general, it can offer better performance than that provided by
standard self-contained references.

The AD584J and AD584K are specified for operation from 0°C
to +70°C, and the AD584S and AD584T are specified for the
−55°C to +125°C range. All grades are packaged in a hermetically
sealed, eight-terminal TO-99 metal can, and the AD584J and
AD584K are also available in an 8-lead PDI P.
PRODUCT HIGHLIGHTS
1. The flexibility of the AD584 eliminates the need to design-
in 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 overtemperature
without the use of external components.
3. The AD584 can be operated in a 2-terminal Zener mode at
a 5 V 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 MIL-STD-
883. Refer to the Analog Devices current AD584/883B data
sheet for detailed specifications. This can be found under the
Additional Data Sheets section of the AD584 product page.
