GENERAL DESCRIPTION
The ADR01, ADR02, ADR03, and ADR06 are precision 10 V,
5 V, 2.5 V, and 3.0 V band gap voltage references featuring high
accuracy, high stability, and low power. The parts are housed in
tiny SC70-5 and TSOT-5 packages, as well as the SOIC-8
versions. The SOIC-8 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-constraint 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
SC70-5, TSOT-5, and SOIC-8 packages with A and B grade
selections. All parts are specified over the extended industrial
(–40°C to +125°C) temperature range.
1
ADR01, ADR02, and ADR03 are component-level compatible with REF01,
REF02, and REF03, respectively. No guarantees for system-level compatibility
are implied. SOIC-8 versions of ADR01/ADR02/ADR03 are pin-to-pin
compatible with SOIC-8 versions of REF01/REF02/REF03, respectively, with
the additional temperature monitoring function.

θJA is specified for the worst-case conditions, that is, θJA is specified for
devices soldered in circuit boards for surface-mount packages.
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.
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 these products feature
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.

ADR01/ADR02/ADR03/ADR06
PARAMETER DEFINITIONS
Temperature Coefficient
Thermal Hysteresis
The change of output voltage with respect to operating temperature changes normalized by the output voltage at 25°C. This
parameter is expressed in ppm/°C and can be determined by the
following equation:
Defined as the change of output voltage after the device is
cycled through temperature from +25°C to –40°C to +125°C
and back to +25°C. This is a typical value from a sample of parts
put through such a cycle.
TCVO [ ppm / °C ] =
VO (T2 ) − VO (T1 )
× 10 6
VO ( 25°C ) × T2 − T1
VO _ HYS = VO ( 25°C ) − VO _ TC
VO _ HYS [ ppm ] =
where:
VO(25°C) = VO at 25°C
VO(T1) = VO at Temperature 1
VO(T2) = VO at Temperature 2
Line Regulation
The change in output voltage due to a specified change in input
voltage. This parameter accounts for the effects of self-heating.
Line regulation is expressed in either percent per volt, partsper-million per volt, or microvolts per volt change in input
voltage.
Load Regulation
The change in output voltage due to a specified change in load
current. This parameter accounts for the effects of self-heating.
Load regulation is expressed in either microvolts per milliampere,
parts-per-million per milliampere, or ohms of dc output
resistance.
Long-Term Stability
Typical shift of output voltage at 25°C on a sample of parts
subjected to a test of 1,000 hours at 25°C:
∆VO = VO (t0 ) − VO (t1 )
∆VO [ ppm] =
VO (t0 ) − VO (t1 )
× 10 6
VO (t0 )
where:
VO(t0) = VO at 25°C at Time 0
VO(t1) = VO at 25°C after 100 hours of operation at 25°C
VO ( 25°C ) − VO _ TC
VO ( 25°C )
× 10 6
where:
VO(25°C) = VO at 25°C
VO_TC = VO at 25°C after temperature cycle at +25°C to –40°C to
+125°C and back to +25°C
NOTES
Input Capacitor
Input capacitors are not required on the ADR01/ADR02/
ADR03/ADR06. There is no limit for the value of the capacitor
used on the input, but a 1 µF to 10 µF capacitor on the input
improves transient response in applications where the supply
suddenly changes. An additional 0.1 µF in parallel also helps to
reduce noise from the supply.
Output Capacitor
The ADR01/ADR02/ADR03/ADR06 do not require output
capacitors for stability under any load condition. An output
capacitor, typically 0.1 µF, filters out any low level noise voltage
and does not affect the operation of the part. On the other hand,
the load transient response can be improved with an additional
1 µF to 10 µF output capacitor in parallel. A capacitor here acts
as a source of stored energy for a sudden increase in load
current. The only parameter that degrades by adding an output
capacitor is the turn-on time, and it depends on the size of the
capacitor chosen.
The majority of the shift is seen in the first 200 hours, and,
as time goes by, the drift decreases significantly. So for the
subsequent 1,000 hours’ time points, this drift is much smaller
than the first.

APPLICATIONS
These devices are standard band gap references. 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 V, 5 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 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 V/5 V/2.5 V/3.0 V. For finer
adjustment, a series resistor of 470 kΩ can be added. With the
configuration shown in Figure 36, 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 resistors are relatively low.

The ADR01/ADR02/ADR03/ADR06 are high precision, low
drift 10 V, 5 V, 2.5 V, and 3.0 V voltage references available in an
ultracompact footprint. The SOIC-8 version of the devices is a
drop-in replacement of the REF01/REF02/ REF03 sockets with
improved cost and performance.

Temperature Monitoring
As described previously, the ADR01/ADR02/ADR03/ADR06
provide a TEMP output (Pin 3) 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 37). A voltage change of 39.2 mV at the
TEMP pin corresponds to a 20°C change in temperature.
Figure 34. Simplified Schematic Diagram
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
The devices can be used without any external components to
achieve the specified performance. Because of the internal op
amp amplifying the band gap cell to 10 V/5 V/2.5 V/3.0 V,
power supply decoupling helps the transient response of the
ADR01/ADR02/ADR03/ADR06. As a result, a 0.1 µF ceramic
type decoupling capacitor should be applied as close as possible

LOW COST CURRENT SOURCE
0.80
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 24. As a result, a current source can be configured as
shown in Figure 40 where ISET = (VOUT – VL)/RSET. IL is simply
the sum of ISET and IQ. Although simple, IQ varies typically from
0.55 to 0.65 mA, limiting this circuit to general-purpose
applications.

Figure 37. 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 would result in
less than a 100 µV change in ∆VOUT (see Figure 38). Without
buffering, even tens of microamps drawn from the TEMP pin
can cause VOUT to fall out of specification.

NEGATIVE REFERENCE
Without using any matching resistors, a negative reference can
be configured as shown in Figure 39. For the ADR01, the voltage difference between VOUT and GND is 10 V. Because VOUT is
at virtual ground, U2 closes the loop by forcing the GND pin to
be the negative reference node. U2 should be a precision op
amp with a low offset voltage characteristic.

To optimize the resolution of this circuit, dual-supply op amps
should be used because the ground potential of ADR02 can
swing from –5 V at zero scale to VL at full scale of the potentiometer setting.

in the range of 1 pF to 10 pF should be connected between VP

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 to 20 mA current
transmitter in the industrial control market (see Figure 42). This
circuit employs a Howland current pump at the output, which
yields 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

In this circuit, an ADR01 provides the stable 10.000 V reference
for the AD5544 quad 16-bit DAC. The resolution of the adjustable current is 0.3 µA/step, and the total worst-case INL error is
merely 4 LSB. 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 43 with measurement taken at 25°C
and 70°C; total system error of 4 LSB 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 44. 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 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.

In this circuit, the AD8512 is capable of delivering 20 mA of
current, and the voltage compliance approaches 15 V.
The Howland current pump yields a potentially infinite output
impedance, which is highly desirable, but resistance matching is
critical in this application. The output impedance can be determined using Equation 3. As can be seen by this equation, if the
resistors are perfectly matched, ZO is infinite. On the other hand,
if they are not matched, ZO is either positive or negative. If the
