GENERAL DESCRIPTION
supply of 300 mV above the output. Their advanced design
eliminates the need for external capacitors, which further
reduces board space and system cost. The combination of low
power operation, small size, and ease of use makes the ADR36x
precision voltage references ideally suited for battery-operated
applications.
The ADR360/ADR361/ADR363/ADR364/ADR365/ADR366
are precision 2.048 V, 2.5 V, 3.0 V, 4.096 V, 5.0 V, and 3.3 V band
gap voltage references that offer low power and high precision
in tiny footprints. Using patented temperature drift curvature
correction techniques from Analog Devices, Inc., the ADR36x
references achieve a low temperature drift of 9 ppm/°C in a
TSOT package.
See the Ordering Guide for automotive grades.
The ADR36x family of micropower, low dropout voltage
references provides a stable output voltage from a minimum

THEORY OF OPERATION
DEꢀICE POWER DISSIPATION CONSIDERATIONS
Band gap references are the high performance solution for low
supply voltage and low power voltage reference applications,
and the ADR36x family is no exception. The uniqueness of
these products lies in their architecture. The ideal zero TC band
gap voltage is referenced to the output, not to ground (see
Figure 32). Therefore, if noise exists on the ground line, it is
greatly attenuated on VOUT. The band gap cell consists of the
PNP pair Q53 and Q52 running at unequal current densities.
The difference in VBE results in a voltage with a positive TC,
which is amplified by a ratio of
The ADR36x family is capable of delivering load currents to
5 mA with an input voltage ranging from 2.348 V (ADR360
only) to 18 V. When this device is used in applications with
large input voltages, care should be taken to avoid exceeding the
specified maximum power dissipation or junction temperature
because it may result in premature device failure. Use the
following formula to calculate a device’s maximum junction
temperature or dissipation:
TJ −TA
PD =
R59
θJA
2×
R54
where:
This PTAT voltage, combined with the VBE of Q53 and Q52,
produces the stable band gap voltage.
TJ and TA are the junction and ambient temperatures, respectively.
PD is the device power dissipation.
θJA is the device package thermal resistance.
Reduction in the band gap curvature is performed by the ratio
of Resistor R44 and Resistor R59, one of which is linearly
temperature dependent. Precision laser trimming and other
patented circuit techniques are used to further enhance the drift
performance.
INPUT CAPACITOR
Input capacitors are not required on the ADR36x. 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 capacitor in parallel also helps reduce noise from the supply.

The ADR36x does not require output capacitors for stability under
any load condition. An output capacitor, typically 0.1 μF, filters
out low level noise voltage and does not affect the operation of
the part. On the other hand, the load transient response can
improve with an additional 1 μF to 10 μF output capacitor placed
in parallel with the 0.1 μF capacitor. The additional capacitor
acts as a source of stored energy for a sudden increase in load
current, and the only parameter that degrades is the turn-on
time. The amount of degradation depends on the size of the
capacitor chosen.

APPLICATIONS INFORMATION
Two reference ICs are used and fed from an unregulated input,
VIN. The outputs of the individual ICs are connected in series,
BASIC ꢀOLTAGE REFERENCE CONNECTION
The circuit in Figure 33 illustrates the basic configuration for
the ADR36x family. Decoupling capacitors are not required for
circuit stability. The ADR36x family is capable of driving
capacitive loads from 0 μF to 10 μF. However, a 0.1 μF ceramic
output capacitor is recommended to absorb and deliver the
charge, as is required by a dynamic load.
which provides two output voltages, VOUT1 and VOUT2. VOUT1 is
the terminal voltage of U1, and VOUT2 is the sum of this voltage
and the terminal voltage of U2. U1 and U2 are chosen for the
two voltages that supply the required outputs (see Table 10). For
example, if both U1 and U2 are ADR361s, VOUT1 is 2.5 V and
VOUT2 is 5.0 V.

Figure 33. Basic Configuration for the ADR36x Family
A negative reference is easily generated by adding an op amp,
A1 (see Figure 35). VOUTF and VOUTS are at virtual ground and
therefore the negative reference can be taken directly from the
output of the op amp. The op amp must be dual-supply, low
offset, and rail-to-rail if the negative supply voltage is close to
the reference output.
Stacking Reference ICs for Arbitrary Outputs
Some applications require two reference voltage sources, which
are a combined sum of standard outputs. Figure 34 shows how
this stacked output reference can be implemented.

General-Purpose Current Source
Trim Terminal
Often in low power applications, the need arises for a precision
current source that can operate on low supply voltages. The
ADR36x can be configured as a precision current source (see
Figure 36). The circuit configuration illustrated is a floating
current source with a grounded load. The output voltage of the
reference is bootstrapped across RSET, which sets the output
current of the load. With this configuration, circuit precision is
maintained for load currents ranging from the reference’s
supply current, typically 150 μA, up to approximately 5 mA.
The ADR36x 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 the standard voltage option. Resistor R1 is
used for fine adjustments and can be omitted if desired. The
resistor values should be carefully chosen to ensure that the
maximum current drive of the part is not exceeded.
