GENERAL DESCRIPTION
The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V,
5.0 V, 2.5 V, and 3.0 V band gap voltage references featuring high
accuracy, high stability, and low power consumption. The parts
are housed in tiny, 5-lead SC70 and TSOT packages, as well as
in 8-lead SOIC versions. The SOIC versions of the ADR01,
ADR02, and ADR03 are drop-in replacements1 to the industry-
standard REF01, REF02, and REF03. The small footprint and
wide operating range make the ADR0x references ideally suited
for general-purpose and space-constrained applications.
With an external buffer and a simple resistor network, the
TEMP terminal can be used for temperature sensing and
approximation. A TRIM terminal is provided on the devices for
fine adjustment of the output voltage.
The ADR01, ADR02, ADR03, and ADR06 are compact, low
drift voltage references that provide an extremely stable output
voltage from a wide supply voltage range. They are available in
5-lead SC70 and TSOT packages, and 8-lead SOIC packages
with A, B, and C grade selections. All parts are specified over
the extended industrial (–40°C to +125°C) temperature range.
The ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead
SOIC are qualified for automotive applications.

1 ADR01, ADR02, and ADR03 are component-level compatible with REF01, REF02, and REF03, respectively. No guarantees for system-level compatibility are implied.
SOIC versions of ADR01/ADR02/ADR03 are pin-to-pin compatible with 8-lead SOIC versions of REF01/REF02/REF03, respectively, with the additional temperature
monitoring function.

TERMINOLOGY
Dropout Voltage (VDO)
Dropout voltage, sometimes referred to as supply voltage head-
room or supply output voltage differential, is defined as the
minimum voltage differential between the input and output
necessary for the device to operate, such as
VDO = (VIN – VOUT)min|IL = Constant
Because the dropout voltage depends upon the current passing
through the device, it is always specified for a given load current.
Temperature Coefficient (TCVO)
The temperature coefficient relates the change in output voltage
to the change in ambient temperature of the device, as normalized
by the output voltage at 25°C. This parameter is expressed in
ppm/°C and can be determined by the following equation:

VOUT(T1) is the output voltage at Temperature 1.
VOUT(T2) is the output voltage at Temperature 2.
Output Voltage Hysteresis (ΔVOUT_HYS)
Output voltage hysteresis represents the change in output
voltage after the device is exposed to a specified temperature
cycle. This may be expressed as either a shift in voltage or a
difference in parts per million from the nominal output as follows:
VOUT_HYS = VOUT(25°C) – VOUT_TC [V]

where:
VOUT(25°C) is the output voltage at 25°C.
VOUT_TC is the output voltage after temperature cycling.
Thermal hysteresis occurs as a result of forces exhibited upon
the internal die by its packaging. The effect is more pronounced
in parts with smaller packages.
Long-Term Stability (ΔVOUT_LTD)
Long-term stability refers to the shift in output voltage at 25°C
after 1000 hours of operation in a 25°C environment. This may
also be expressed as either a shift in voltage or a difference in
parts per million from the nominal output as follows:
ΔVOUT_LTD = |VOUT(t1) – VOUT(t0)| [V]

VOUT(t1) is the VOUT at 25°C after 1000 hours of operation at 25°C.
Line Regulation
Line regulation refers to the change in output voltage in
response to a given change in input voltage, and is expressed in
either percent per volt, parts per million per volt, or microvolt
per volt change in input voltage. This parameter accounts for
the effects of self-heating.
Load Regulation
Load regulation refers to the change in output voltage in
response to a given change in load current, and is expressed
in either microvolts per milliampere, parts per million per
milliampere, or ohms of dc output resistance. This parameter
accounts for the effects of self-heating.

APPLICATIONS INFORMATION
OVERVIEW
The ADR01/ADR02/ADR03/ADR06 are high precision, low
drift 10.0 V, 5.0 V, 2.5 V, and 3.0 V voltage references available
in an ultracompact footprint. The 8-lead SOIC versions of the
devices are drop-in replacements of the REF01/REF02/REF03
sockets with improved cost and performance.
These devices are standard band gap references (see Figure 34).
The band gap cell contains two NPN transistors (Q18 and Q19)
that differ in emitter area by 2×. The difference in their VBE
produces a proportional-to-absolute temperature current (PTAT)
in R14, and, when combined with the VBE of Q19, produces a
band gap voltage, VBG, that is almost constant in temperature.
With an internal op amp and the feedback network of R5 and
R6, VO is set precisely at 10.0 V, 5.0 V, 2.5 V, and 3.0 V for the
ADR01, ADR02, ADR06, and ADR03, respectively. Precision
laser trimming of the resistors and other proprietary circuit
techniques are used to further enhance the initial accuracy,
temperature curvature, and drift performance of the ADR01/
ADR02/ADR03/ADR06.
The PTAT voltage is made available at the TEMP pin of the
ADR01/ADR02/ADR03/ADR06. It has a stable 1.96 mV/°C
temperature coefficient, such that users can estimate the
temperature change of the device by knowing the voltage
change at the TEMP pin.
APPLYING THE ADR01/ADR02/ADR03/ADR06
Input and Output Capacitors
Although the ADR01/ADR02/ADR03/ADR06 are designed to
function stably without any external components, connecting a
0.1 μF ceramic capacitor to the output is highly recommended
to improve stability and filter out low level voltage noise. An
additional 1 μF to 10 μF electrolytic, tantalum, or ceramic
capacitor can be added in parallel to improve transient per-
formance in response to sudden changes in load current;
however, the designer should keep in mind that doing so
increases the turn-on time of the device.
A 1 μF to 10 μF electrolytic, tantalum or ceramic capacitor can
also be connected to the input to improve transient response in
applications where the supply voltage may fluctuate. An addi-
tional 0.1 μF ceramic capacitor should be connected in parallel
to reduce supply noise. Mount both input and output capacitors
as close to the device pins as possible.
Output Adjustment
The ADR01/ADR02/ADR03/ADR06 trim terminal can be used
to adjust the output voltage over a nominal voltage. This feature
allows a system designer to trim system errors by setting the
reference to a voltage other than 10.0 V/5.0 V/2.5 V/3.0 V. For
finer adjustment, add a series resistor of 470 kΩ. With the con-
figuration shown in Figure 35, the ADR01 can be adjusted from
9.70 V to 10.05 V, the ADR02 can be adjusted from 4.95 V to
5.02 V, the ADR06 can be adjusted from 2.8 V to 3.3 V, and the
ADR03 can be adjusted from 2.3 V to 2.8 V. Adjustment of the
output does not significantly affect the temperature performance
of the device, provided the temperature coefficients of the resis-
tors are relatively low.

Temperature Monitoring
As described at the end of the Overview section, the ADR01/
ADR02/ADR03/ADR06 provide a TEMP output (Pin 1 in Figure 1
and Pin 3 in Figure 2) that varies linearly with temperature.
This output can be used to monitor the temperature change in the
system. The voltage at VTEMP is approximately 550 mV at 25°C,
and the temperature coefficient is approximately 1.96 mV/°C
(see Figure 36). A voltage change of 39.2 mV at the TEMP pin
corresponds to a 20°C change in temperature.

Figure 36. Voltage at TEMP Pin vs. Temperature
The TEMP function is provided as a convenience rather than a
precise feature. Because the voltage at the TEMP node is
acquired from the band gap core, current pulling from this pin
has a significant effect on VOUT. Care must be taken to buffer the
TEMP output with a suitable low bias current op amp, such as
the AD8601, AD820, or OP1177, all of which result in less than
a 100 µV change in ∆VOUT (see Figure 37). Without buffering,
even tens of microamps drawn from the TEMP pin can cause
VOUT to fall out of specification.

LOW COST CURRENT SOURCE
Unlike most references, the ADR01/ADR02/ADR03/ADR06
employ an NPN Darlington in which the quiescent current
remains constant with respect to the load current, as shown in
Figure 23. As a result, a current source can be configured as
shown in Figure 38 where ISET = (VOUT − VL)/RSET. IL is simply
the sum of ISET and IQ. Although simple, IQ varies typically from
0.55 mA to 0.65 mA, limiting this circuit to general-purpose
applications.

Alternatively, a precision current source can be implemented
with the circuit shown in Figure 39. By adding a mechanical or
digital potentiometer, this circuit becomes an adjustable current
source. If a digital potentiometer is used, the load current is
simply the voltage across Terminal B to Terminal W of the
digital potentiometer divided by RSET.

To optimize the resolution of this circuit, dual-supply op amps
should be used because the ground potential of ADR02 can
swing from −5.0 V at zero scale to VL at full scale of the
potentiometer setting.

PROGRAMMABLE 4 mA TO 20 mA CURRENT
TRANSMITTER
Because of their precision, adequate current handling, and small
footprint, the devices are suitable as the reference sources for
many high performance converter circuits. One of these
applications is the multichannel 16-bit, 4 mA to 20 mA current
transmitter in the industrial control market (see Figure 40).
This circuit employs a Howland current pump at the output to
yield better efficiency, a lower component count, and a higher
voltage compliance than the conventional design with op amps
and MOSFETs. In this circuit, if the resistors are matched such
that R1 = R1′, R2 = R2′, R3 = R3′, the load current is

where D is similarly the decimal equivalent of the DAC input

According to Equation 2, R3′ can be used to set the sensitivity.
R3′ can be made as small as necessary to achieve the current
needed within U4 output current driving capability. Alter-
natively, other resistors can be kept high to conserve power.
In this circuit, the AD8512 is capable of delivering 20 mA of
current, and the voltage compliance approaches 15.0 V.

The Howland current pump yields a potentially infinite output
impedance, that is highly desirable, but resistance matching is
critical in this application. The output impedance can be deter-
mined using Equation 3. As shown by this equation, if the
resistors are perfectly matched, ZO is infinite. Alternatively, if
they are not matched, ZO is either positive or negative. If the
latter is true, oscillation can occur. For this reason, connect
Capacitor C1 in the range of 1 pF to 10 pF between VP and the
output terminal of U4 to filter any oscillation.

In this circuit, an ADR01 provides the stable 10.000 V reference
for the AD5544 quad 16-bit DAC. The resolution of the adjust-
able current is 0.3 µA/step; the total worst-case INL error is
merely 4 LSBs. Such error is equivalent to 1.2 µA or a 0.006%
system error, which is well below most systems’ requirements.
The result is shown in Figure 41 with measurement taken at 25°C
and 70°C; total system error of 4 LSBs at both 25°C and 70°C.

PRECISION BOOSTED OUTPUT REGULATOR
A precision voltage output with boosted current capability can
be realized with the circuit shown in Figure 42. In this circuit,
U2 forces VO to be equal to VREF by regulating the turn-on of
N1, thereby making the load current furnished by VIN. In this
configuration, a 50 mA load is achievable at VIN of 15.0 V.
Moderate heat is generated on the MOSFET, and higher current
can be achieved with a replacement of a larger device. In
addition, for a heavy capacitive load with a fast edging input
signal, a buffer should be added at the output to enhance the
transient response.
