GENERAL DESCRIPTION
Designed for space-critical applications, the ADR520/ADR525/ ADR530/ADR540/ADR550 are high precision shunt voltage references, housed in ultrasmall SC70 and SOT-23 packages. These references feature low temperature drift of 40 ppm/C, an initial accuracy of better than 0.2%, and ultralow output noise of 14 V p-p. Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V, the ADR5xx's advanced design eliminates the need for compensation by an external capacitor, yet the references are stable with any capacitive load. The minimum operating current increases from a mere 50 A to a maximum of 10 mA. This low operating current and ease of use make these references ideally suited for handheld, battery-powered applications. A TRIM terminal is available on the ADR5xx to allow adjustment of the output voltage over a 0.5% range, without affecting the temperature coefficient of the device. This feature provides users with the flexibility to trim out any system errors.

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 this product features 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.

ADR520/ADR525/ADR530/ADR540/ADR550 PARAMETER DEFINITIONS
TEMPERATURE COEFFICIENT
Temperature coefficient is defined as the change in output voltage with respect to operating temperature changes, and is normalized by an output voltage of 25C. This parameter is expressed in ppm/C, and is determined by the following equation:
THERMAL HYSTERESIS
Thermal hysteresis is defined as the change in output voltage after the device is cycled through temperatures ranging from +25C to -40C, then to +85C, and back to +25C. The following equation expresses a typical value from a sample of parts put through such a cycle:
VO (T2 ) - VO (T1 ) ppm 6 TCVO C = V (25C ) x (T - T ) x 10 2 1 O where: VO(25C) = VO at 25C. VO(T1) = VO at Temperature 1. VO(T2) = VO at Temperature 2.
(1)
VO _ HYS = VO (25C ) - VO _ TC VO _ HYS [ppm] = where: VO(25C) = VO at 25C.
VO (25C ) - VO _ TC VO (25C )
x 10 6
(2)
VO_TC = VO at 25C after a temperature cycle from +25C to -40C, then to +85C, and back to +25C.

ADR520/ADR525/ADR530/ADR540/ADR550 THEORY OF OPERATION
The ADR520/ADR525/ADR530/ADR540/ADR550 use the band gap concept to produce a stable, low temperature coefficient voltage reference suitable for high accuracy data acquisition components and systems. The devices use the physical nature of a silicon transistor base-emitter voltage in the forward-biased operating region. All such transistors have approximately a -2 mV/C temperature coefficient (TC), making them unsuitable for direct use as a low temperature coefficient reference. Extrapolation of the temperature characteristic of any one of these devices to absolute zero (with the collector current proportional to the absolute temperature), however, reveals that its VBE approaches approximately the silicon band gap voltage. Thus, if a voltage develops with an opposing temperature coefficient to sum the VBE, a zero temperature coefficient reference results. The ADR5xx circuit shown in Figure 18 provides such a compensating voltage (V1) by driving two transistors at different current densities and amplifying the resultant VBE difference (VBE, which has a positive temperature coefficient). The sum of VBE and V1 provides a stable voltage reference over temperature.

*
The RBIAS must be large enough so that IIN does not exceed 10 mA when the supply voltage is at its maximum value and the load current is at its minimum value.
Given these conditions, the RBIAS is determined by the supply voltage (VCC), the ADR5xx load and operating current (IL and IQ), and the ADR5xx output voltage (VOUT).

APPLICATIONS
The ADR520/ADR525/ADR530/ADR540/ADR550 are a series of precision shunt voltage references. They are designed to operate without an external capacitor between the positive and negative terminals. If a bypass capacitor is used to filter the supply, the references remains stable. All shunt voltage references require an external bias resistor (RBIAS) between the supply voltage and the reference (see Figure 19). The RBIAS sets the current that flows through the load (IL) and the reference (IIN). Because the load and the supply voltage can vary, the RBIAS needs to be chosen based on the following considerations:
*
Output Voltage Trim
The ADR5xx TRIM terminal can be used to adjust the output voltage over a range of 0.5%. This allows systems designers to trim system errors by setting the reference to a voltage other than the preset output voltage. An external mechanical or electrical potentiometer can be used for this adjustment. Figure 21 illustrates how the output voltage can be trimmed by using the AD5273, an Analog Devices 10 k potentiometer.

The RBIAS must be small enough to supply the minimum IIN current to the ADR5xx, even when the supply voltage is at its minimum value and the load current is at its maximum value.

Stacking ADR5xx for User-Definable Outputs
Multiple ADR5xx parts can be stacked together to allow the user to obtain a desired higher voltage. Figure 22a shows three ADR550s configured to give 15 V. The bias resistor, RBIAS, is chosen using Equation 3, noting that the same bias current will flow through all the shunt references in series. Figure 22b shows three ADR550s stacked together to give -15 V. RBIAS is calculated in the same manner as before. Parts of different voltages can also be added together, i.e., an ADR525 and an ADR550 can be added together to give an output of +7.5 V or -7.5 V, as desired. Note, however, that the initial accuracy error is now the sum of the errors of all the stacked parts, as are the tempco and output voltage change versus input current.
Adjustable Precision Voltage Source
The ADR5xx, combined with a precision low input bias op amp, such as the AD8610, can be used to output a precise adjustable voltage. Figure 23 illustrates the implementation of this application using the ADR5xx. The output of the op amp, VOUT, is determined by the gain of the circuit, which is completely dependant on the resistors, R1 and R2.
VOUT = (1 + R2/R1)VREF
An additional capacitor, C1, in parallel with R2, can be added to filter out high frequency noise. The value of C1 is dependent on the value of R2.
