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.

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

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.

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.

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.

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.

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.

THEORY OF OPERATION

APPLYING THE AD584

omit R2; choose its value to limit the output to a value that can

be tolerated by the load circuits. If R2 is zero, adjusting R1 to its

lower limit results in a loss of control over the output voltage.

When precision voltages are set at levels other than the standard

outputs, account for the 20% absolute tolerance in the internal

resistor ladder.

With power applied to Pin 8 and Pin 4 and all other pins open,

the AD584 produces a buffered nominal 10.0 V output between

Pin 1 and Pin 4 (see Figure 3). The stabilized output voltage can

be reduced to 7.5 V, 5.0 V, or 2.5 V by connecting the programming

pins as shown in Table 4.

Table 4.

Output

Voltage (V) Pin Programming

Alternatively, the output voltage can be raised by loading the

2.5 V tap with R3 alone. The output voltage can be lowered by

connecting R4 alone. Either of these resistors can be a fixed

resistor selected by test or an adjustable resistor. In all cases, the

resistors should have a low temperature coefficient to match the

AD584 internal resistors, which have a negative temperature

coefficient less than 60 ppm/°C. If both R3 and R4 are used,

these resistors should have matching temperature coefficients.

Connect the 5.0 V pin (Pin 2) to the output pin (Pin 1).

Connect the 2.5 V pin (Pin 3) to the output pin (Pin 1).

The options shown in Table 4 are available without the use of any

additional components. Multiple outputs using only one AD584

can be provided by buffering each voltage programming pin

with a unity-gain, noninverting op amp.

When only small adjustments or trims are required, the circuit

in Figure 4 offers better resolution over a limited trim range. The

circuit can be programmed to 5.0 V, 7.5 V, or 10 V, and it can be

adjusted by means of R1 over a range of about 200 m V. To trim

the 2.5 V output option, R2 (see Figure 4) can be reconnected to

the band gap reference (Pin 6). In this configuration, limit the

adjustment to 100 mV to avoid affecting the performance of

the AD584.

The AD584 can also be programmed over a wide range of output

voltages, including voltages greater than 10 V, by the addition

of one or more external resistors. Figure 3 illustrates the general

adjustment procedure, with approximate values given for the

internal resistors of the AD584. The AD584 may be modeled

as an op amp with a noninverting feedback connection, driven

by a high stability 1.215 V band gap reference (see Figure 5 for

When the feedback ratio is adjusted with external resistors, the

output amplifier can be made to multiply the reference voltage

by almost any convenient amount, making popular outputs of

10.24 V, 5.12 V, 2.56 V, or 6.3 V easy to obtain. The most general

adjustment (which gives the greatest range and poorest resolution)

uses R1 and R2 alone (see Figure 3). As R1 is adjusted to its upper

limit, the 2.5V pin (Pin 3) is connected to the output, which

reduces to 2.5 V. As R1 is adjusted to its lower limit, the output

voltage rises to a value limited by R2. For example, if R2 is

approximately 6 kΩ, the upper limit of the output range is

output current characteristics of the device. Source current is

displayed as negative current in the figure, and sink current is

displayed as positive current. The short-circuit current (that is,

0 V output) is about 28 mA; however, when shorted to 15 V, the

sink current goes to approximately 20 mA.

Each AD584 is tested at three temperatures over the −55°C to

+125°C range to ensure that each device falls within the maximum

error band (see Figure 6) specified for a particular grade (that is, S

and T grades); three-point measurement guarantees performance

within the error band from 0°C to 70°C (that is, J and K grades).

The error band guaranteed for the AD584 is the maximum

deviation from the initial value at 25°C. Thus, given the grade

of the AD584, the maximum total error from the initial tolerance

plus the temperature variation can easily be determined. For

example, for the AD584T, the initial tolerance is 10 mV, and

the error band is 15 mV. Therefore, the unit is guaranteed to

be 10.000 V 25 mV from −55°C to +125°C.

DYNAMIC PERFORMANCE

Many low power instrument manufacturers are becoming

increasingly concerned with the turn-on characteristics of the

components being 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. Figure 8

displays the turn-on characteristic of the AD584. Figure 8 is

generated from cold-start operation and represents the true

turn-on waveform after an extended period with the supplies off.

Figure 8 shows both the coarse and fine transient characteristics of

the device; the total settling time to within 10 mV is about

180 µs, and there is no long thermal tail appearing after the point.

NOISE FILTERING

USING THE STROBE TERMINAL

The bandwidth of the output amplifier in the AD584 can be

reduced to filter output noise. A capacitor ranging between 0.01 µF

and 0.1 µF connected between the CAP and V_BGterminals further

reduces the wideband and feedthrough noise in the output of

the AD584, as shown in Figure 9 and Figure 10. However, this

tends to increase the turn-on settling time of the device; therefore,

allow for ample warm-up time.

The AD584 has a strobe input that can be used to zero the output.

This unique feature permits a variety of new applications in

signal and power conditioning circuits.

Figure 11 illustrates the strobe connection. A simple NPN switch

can be used to translate a TTL logic signal into a strobe of the

output. The AD584 operates normally when there is no current

drawn from Pin 5. Bringing this terminal low, to less than 200 mV,

allows the output voltage to go to zero. In this mode, the AD584

is not required to source or sink current (unless a 0.7 V residual

output is permissible). If the AD584 is required to sink a transient

current while strobe is off, limit the strobe terminal input current

by a 100 Ω resistor, as shown in Figure 11.

The strobe terminal tolerates up to 5 µA leakage, and its driver

The AD584 can also use an NPN or NPN Darlington transistor to

boost its output current. Simply connect the 10 V output terminal

of the AD584 to the base of the NPN booster and take the

output from the booster emitter, as shown in Figure 13. The

5.0V pin or the 2.5V pin must connect to the actual output in

this configuration. Variable or adjustable outputs (as shown in

Figure 3 and Figure 4) can be combined with a 5.0 V connection to

obtain outputs above 5.0 V.

The temperature characteristics and long-term stability of the

device is essentially the same as that of a unit used in standard

The AD584 can also be used in 2-terminal mode to develop a

positive reference. V_INand V_OUTare tied together and to the

positive supply through an appropriate supply resistor. The

performance characteristics are similar to those of a negative

2-terminal connection. The only advantage of this connection

over the standard 3-terminal connection is that a lower primary

supply can be used, as low as 0.5 V above the desired output

voltage. This type of operation requires considerable attention

to load and to the primary supply regulation to ensure that the

AD584 always remains within its regulating range of 1 mA to

5 mA (2 mA to 5 mA for operation beyond 85°C).

THE AD584 AS A CURRENT LIMITER

The AD584 represents an alternative to current limiter diodes

that require factory selection to achieve a desired current. Use of

current limiting diodes often results in temperature coefficients

of 1%/°C. Use of the AD584 in this mode is not limited to a set

current limit; it can be programmed from 0.75 mA to 5 mA

with the insertion of a single external resistor (see Figure 14).

The minimum voltage required to drive the connection is 5 V.

10 V REFERENCE WITH MULTIPLYING CMOS DACs

OR ADCs

The AD584 is ideal for application with the AD7533 10-bit

multiplying CMOS DAC, especially for low power applications.

It is equally suitable for the AD7574 8-bit ADC. In the standard

hook-up, as shown in Figure 16, the standard output voltages are

inverted by the amplifier/DAC configuration to produce converted

voltage ranges. For example, a +10 V reference produces a 0 V to

−10 V range. If an OP1177 amplifier is used, total quiescent

supply current is typically 2 mA.

The AD584 can also be used in a 2-terminal Zener mode to

Figure 15, the V_INand V_OUTterminals are connected together to

output is now taken from the COMMON pin instead of V_OUT. With

1 mA flowing through the AD584 in this mode, a typical unit

shows a 2 mV increase in the output level over that produced in

3-terminal mode. Also, note that the effective output impedance in

this connection increases from 0.2 Ω typical to 2 Ω. It is essential

to arrange the output load and the supply resistor, R_S, so that

the net current through the AD584 is always between 1 mA

and 5 mA (between 2 mA and 5 mA for operation beyond 85°C).

The AD584 is normally used in the −10 V mode with the AD7574

to give a 0 V to +10 V ADC range. This is shown in Figure 17.

Bipolar output applications and other operating details can be

found in the data sheets for the CMOS products.

scale temperature coefficient of 18 ppm/°C more than the

commercial range. The 10 V reference also supplies the normal

1 mA bipolar offset current through the 9.95 kΩ bipolar offset

resistor. The bipolar offset temperature coefficient thus depends

only on the temperature coefficient matching of the bipolar offset

resistor to the input reference resistor and is guaranteed to

3 ppm/°C. Figure 18 demonstrates the flexibility of the AD584

applied to another popular digital-to-analog configuration.

is primarily governed by the temperature tracking of the 19.95 kΩ

resistor and the 5 kΩ/10 kΩ span resistors; this gain temperature

coefficient is guaranteed to 3 ppm/°C. Therefore, using the AD584K

(at 5 ppm/°C) as the 10 V reference guarantees a maximum full-
