GENERAL DESCRIPTION
The AD581 is a 3-pin, temperature compensated, monolithic,
band gap voltage reference that provides a precise 10.00 V output
from an unregulated input level ranging from 12 V to 30 V.
Laser wafer trimming (LWT) is used to trim both the initial
error at +25°C as well as the temperature coefficient, resulting
in high precision performance previously available only in expensive hybrids or oven regulated modules. The 5 mV initial error
tolerance and 5 ppm/°C guaranteed temperature coefficient of
the AD581L is available in a monolithic voltage reference.
The band gap circuit design used in the AD581 offers several
advantages over classical Zener breakdown diode techniques.
Most important, no external components are required to
achieve full accuracy and significant stability to low power
systems. In addition, total supply current to the device,
including the output buffer amplifier (which can supply up
to 10 mA) is typically 750 A. The long-term stability of the
band gap design is equivalent to selected Zener reference
diodes.
The AD581 is recommended for use as a reference for 8-, 10-
or 12-bit digital-to-analog converters (DACs) that require an
external precision reference. The device is also ideal for all types
of analog-to-digital converters (ADCs) up to 14-bit accuracy,
either successive approximation or integrating designs, and can
generally offer better performance than that provided by standard
self-contained references.

The AD581J, AD581K, and AD581L are specified for operation
from 0°C to 70°C; the AD581S, AD581T, and AD581U are
specified for the −55°C to +125°C range. All grades are
packaged in a hermetically sealed 3-pin TO-5 metal can.
PRODUCT HIGHLIGHTS
1. Laser trimming of both initial accuracy and temperature
coefficient results in very low errors over temperature
without the use of external components. The AD581L has
a maximum deviation from 10.000 V of ±7.25 mV from
0°C to 70°C, whereas the AD581U guarantees ±15 mV
maximum total error without external trims from −55°C
to +125°C.
2. Because the laser trimming is done on the wafer prior to
separation into individual chips, the AD581 is extremely
valuable to hybrid designers for its ease of use, lack of
required external trims, and inherent high performance.
3. The AD581 can also be operated in a 2-pin Zener mode to
provide a precision −10 V reference with just one external
resistor to the unregulated supply. The performance in this
mode is nearly equal to that of the standard 3-pin configuration.
4. Advanced circuit design using the band gap concept allows
the AD581 to give full performance with an unregulated
input voltage down to 13 V. With an external resistor, the
device operates with a supply as low as 11.4 V.
5. The AD581 is available in versions compliant with
MILSTD-883. Refer to the military datasheet for detailed
specifications.

APPLYING THE AD581
The AD581 is easy to use in virtually all precision reference
applications. The three pins are simply: primary supply, ground,
and output, with the case grounded. No external components
are required even for high precision applications; the degree of
desired absolute accuracy is achieved simply by selecting the
required device grade. The AD581 requires less than 1 mA quiescent current from an operating supply range of 13 V to 30 V.

An external fine trim may be desired to set the output level to
exactly 10.000 V within less than a millivolt (calibrated to a
main system reference). System calibration may also require a
reference slightly different from 10.00 V. In either case, the
optional trim circuit shown in Figure 3 can offset the output by
up to ±30 mV (with the 22 resistor), if needed, with minimal
effect on other device characteristics.

VOLTAGE VARIATION vs. TEMPERATURE
Some confusion exists in the area of defining and specifying
reference voltage error over temperature. Historically, references
have been characterized using a maximum deviation per degree
Celsius; that is, 10 ppm/°C. However, because of nonlinearities
in temperature characteristics, which originated in standard
Zener references (such as S-type characteristics) manufacturers
opt for the maximum limit error band approach to specify devices.
This technique involves measurement of the output at three,
five, or more different temperatures to guarantee that the output
voltage falls within the given error band. The temperature characteristic of the AD581 consistently follows the S-curve shown in
Figure 5. Three-point measurement of each device guarantees
the error band over the specified temperature range.

The error band which is guaranteed with the AD581 is the
maximum deviation from the initial value at +25°C; this error
band is of more use to a designer than one which simply guarantees
the maximum total change over the entire range (that is, in the
latter definition, all of the changes could occur in the positive
direction). Thus, with a given grade of the AD581, the designer
can easily determine the maximum total error from initial tolerance plus temperature variation (for example, for the AD581T, the
initial tolerance is ±10 mV, the temperature error band is ±15 mV,
thus the unit is guaranteed to be 10.000 V ±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 positive
supply or ground. The output voltage vs. output current characteristics of the device are shown in Figure 6. Source current
is displayed as negative current in the figure; sink current is
positive. Note that the short-circuit current (that is, 0 V output)
is about 28 mA; when shorted to +15 V, the sink current goes to
about 20 mA.

DYNAMIC PERFORMANCE
Many low power instrument manufacturers have been increasingly concerned with the turn-on characteristics of the
components used in their systems. Fast turn-on components 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 7 displays the turn-on characteristic of the AD581. This
characteristic is generated from a 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 mV is about 180 s, and there is no long thermal tail
appearing after the point.

PRECISION HIGH CURRENT SUPPLY CONNECTION FOR REDUCED PRIMARY 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 10 delivers a precision
10 V output with up to 4 A supplied to the load. The 0.1 F
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.

Whereas line regulation is specified down to 13 V, the typical
AD581 works as specified ≤12 V. The current sink capability
allows even lower supply voltage capability such as operation
from 12 V ±5% as shown in Figure 11. The 560 resistor reduces
the current supplied by the AD581 to a manageable level at a

THE AD581 AS A CURRENT LIMITER
The AD581 represents an alternative to current limiter diodes
that require factory selection to achieve a desired current. This
approach often results in temperature coefficients of 1%/°C.
The AD581 approach is not limited to a defined set current
limit; it can be programmed from 0.75 mA to 5 mA with the
insertion of a single external resistor. Of course, the minimum
voltage required to drive the connection is 13 V. The AD580,
which is a 2.5 V reference, can be used in this type of circuit
with compliance voltage down to 4.5 V.

the AD581 is always between 1 mA and 5 mA. For operation to

performance characteristics are similar to those of the negative

the standard 3-pin connection is that a lower primary supply

maintain the AD581 within its regulating range of 1 mA to 5 mA

10 V REFERENCE WITH MULTIPLYING CMOS DACs OR ADCs
The AD581 is ideal for application with the entire AD7533
series of 10- and 12-bit multiplying CMOS DACs, especially for
low power applications. It is equally suitable for the AD7574
8-bit ADC. In the standard hook-up, as shown in Figure 15, the
+10 V reference is inverted by the amplifier/DAC configuration
to produce a 0 V to −10 V range. If an OP1177 amplifier is used,
total quiescent supply current is typically 2 mA. If a 0 V to +10 V
full-scale range is desired, the AD581 can be connected to the
CMOS DAC in its −10 V Zener mode, as shown in Figure 13
(the −10 V
output is connected directly to the V

CMOS DAC). The AD581 is normally used in the −10 V mode

AD565A, like most DACs, is designed to operate with a +10 V
reference element. In the AD565A, this 10 V reference voltage is
converted into a reference current of approximately 0.5 mA via
the internal 19.95 k resistor (in series with the external 100
trimmer). The gain temperature coefficient of the AD565A is
primarily governed by the temperature tracking of the 19.95 k
resistor and the 5 kΩ to10 kΩ span resistors; gain TC is guaranteed to 3 ppm/°C. Thus, using the AD581L (at 5 ppm/°C) as the

reference also supplies the normal 1 mA bipolar offset current

bipolar offset TC depends only on TC matching of the bipolar
offset resistor to the input reference resistor and is guaranteed
to 3 ppm/°C.
