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 PDIP.
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.
Laser trimming of both initial accuracy and temperature
coefficient results in very low errors overtemperature
without the use of external components.
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.
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).
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.
