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 V_OUT. The band gap cell consists of the

PNP pair Q53 and Q52 running at unequal current densities.

The difference in V_BEresults 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:

T_J−T_A

P_D=

R59

θ_JA

2×

R54

where:

This PTAT voltage, combined with the V_BEof Q53 and Q52,

produces the stable band gap voltage.

T_Jand T_Aare the junction and ambient temperatures, respectively.

P_Dis the device power dissipation.

θ_JAis 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,

V_IN. 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, V_OUT1and V_OUT2. V_OUT1is

the terminal voltage of U1, and V_OUT2is 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, V_OUT1is 2.5 V and

V_OUT2is 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). V_OUTFand V_OUTSare 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 R_SET, 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.
