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 in SOIC-8
versions. The SOIC-8 versions of the ADR01, ADR02, and
ADR03 are drop-in replacements
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.

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.

PARAMETER DEFINITIONS AND NOTES

Temperature Coefficient
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

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, parts-per-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

Thermal Hysteresis
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.

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.

ADR01/ADR02/ADR03/ADR06

APPLICATIONS

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.

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 V

produces a

BE

proportional-to-absolute temperature current (PTAT) in R14,
and, when combined with the V
voltage, V

that is almost constant in temperature. With an

BG,

internal op amp and the feedback network

of Q19, produces a band gap

BE

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 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
to the input and output pins of the device. An optional 1 µF to
10 µF bypass capacitor can also be applied at the V
maintain the input under transient disturbance.

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 V/5 V/2.5 V/3.0 V. For

adjustment, a series resistor of 470 kΩ can be added. With

finer
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.

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 V
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.

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 V

. Care must be taken to buffer the

OUT

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 ∆V

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 V

and GND is 10 V. Because V

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.

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 24. As a result, a current source can be configured as

PROGRAMMABLE 4 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 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

where D is similarly the decimal equivalent of the DAC input
code and N is the number of bits of the DAC.

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. On the
other hand, 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 V.

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; 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

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.
