Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and
5.0 V, the ADR5xx’s advanced design eliminates the need for
compensation by an external capacitor, yet the references are
stable with any capacitive load. The minimum operating current
increases from a mere 50 µA to a maximum of 10 mA. This low
operating current and ease of use make these references ideally
suited for handheld, battery-powered applications.
A TRIM terminal is available on the ADR5xx to allow adjustment
of the output voltage over a ±0.5% range, without affecting the
temperature coefficient of the device. This feature provides users
with the flexibility to trim out any system errors.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
θJA is specified for worst-case conditions, i.e., θJA is specified for devices
soldered on circuit boards for surface-mount packages. Contact factory for
latest information on release dates.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

PARAMETER DEFINITIONS
TEMPERATURE COEFFICIENT
THERMAL HYSTERESIS
Temperature coefficient is defined as the change in output
voltage with respect to operating temperature changes, and is
normalized by an output voltage of 25°C. This parameter is
expressed in ppm/°C, and is determined by the following
equation:
Thermal hysteresis is defined as the change in output voltage
after the device is cycled through temperatures ranging from
+25°C to –40°C, then to +85°C, and back to +25°C. The
following equation expresses a typical value from a sample of
parts put through such a cycle:
VO (T2 ) − VO (T1 )

TCVO ⎡⎢
⎣ °C ⎥⎦ VO (25°C ) × (T2 − T1 )
VO _ HYS = VO (25°C ) − VO _ TC

VO _ HYS [ppm] =
VO (25°C ) − VO _ TC

VO(25°C) = VO at 25°C.
VO(T1) = VO at Temperature 1.

THEORY OF OPERATION
The RBIAS must be large enough so that IIN does not exceed
10 mA when the supply voltage is at its maximum value
and the load current is at its minimum value.
Given these conditions, the RBIAS is determined by the supply
voltage (VCC), the ADR5xx load and operating current (IL and
IQ), and the ADR5xx output voltage (VOUT).

VCC − VOUT

The ADR520/ADR525/ADR530/ADR540/ADR550 use the
band gap concept to produce a stable, low temperature
coefficient voltage reference suitable for high accuracy data
acquisition components and systems. The devices use the
physical nature of a silicon transistor base-emitter voltage in the
forward-biased operating region. All such transistors have
approximately a –2 mV/°C temperature coefficient (TC),
making them unsuitable for direct use as a low temperature
coefficient reference. Extrapolation of the temperature
characteristic of any one of these devices to absolute zero (with
the collector current proportional to the absolute temperature),
however, reveals that its VBE approaches approximately the
silicon band gap voltage. Thus, if a voltage develops with an
opposing temperature coefficient to sum the VBE, a zero
temperature coefficient reference results. The ADR5xx circuit
shown in Figure 18 provides such a compensating voltage (V1)
by driving two transistors at different current densities and
amplifying the resultant VBE difference (∆VBE, which has a
positive temperature coefficient). The sum of VBE and V1
provides a stable voltage reference over temperature.
The ADR5xx is suitable for applications where a precise
negative voltage is desired. Figure 20 shows the ADR5xx
configured to provide a negative output.

APPLICATIONS
Output Voltage Trim
The ADR520/ADR525/ADR530/ADR540/ADR550 are a series
of precision shunt voltage references. They are designed to
operate without an external capacitor between the positive and
negative terminals. If a bypass capacitor is used to filter the
supply, the references remains stable.
The ADR5xx TRIM terminal can be used to adjust the output
voltage over a range of ±0.5%. This allows systems designers to
trim system errors by setting the reference to a voltage other
than the preset output voltage. An external mechanical or electrical potentiometer can be used for this adjustment. Figure 21
illustrates how the output voltage can be trimmed by using the
AD5273, an Analog Devices 10 kΩ potentiometer.
•
The RBIAS must be small enough to supply the minimum IIN
current to the ADR5xx, even when the supply voltage is at
its minimum value and the load current is at its maximum
value.

All shunt voltage references require an external bias resistor
(RBIAS) between the supply voltage and the reference (see
Figure 19). The RBIAS sets the current that flows through the load
(IL) and the reference (IIN). Because the load and the supply
voltage can vary, the RBIAS needs to be chosen based on the
following considerations:

Stacking ADR5xx for User-Definable Outputs
Adjustable Precision Voltage Source
Multiple ADR5xx parts can be stacked together to allow the
user to obtain a desired higher voltage. Figure 22a shows three
ADR550s configured to give 15 V. The bias resistor, RBIAS, is
chosen using Equation 3, noting that the same bias current will
flow through all the shunt references in series. Figure 22b shows
three ADR550s stacked together to give –15 V. RBIAS is calculated
in the same manner as before. Parts of different voltages can
also be added together, i.e., an ADR525 and an ADR550 can be
added together to give an output of +7.5 V or –7.5 V, as desired.
Note, however, that the initial accuracy error is now the sum of
the errors of all the stacked parts, as are the tempco and output
voltage change versus input current.
The ADR5xx, combined with a precision low input bias op amp,
such as the AD8610, can be used to output a precise adjustable
voltage. Figure 23 illustrates the implementation of this
application using the ADR5xx. The output of the op amp, VOUT,
is determined by the gain of the circuit, which is completely
dependant on the resistors, R1 and R2.
VOUT = (1 + R2/R1)VREF
An additional capacitor, C1, in parallel with R2, can be added to
filter out high frequency noise. The value of C1 is dependent on
the value of R2.
