These voltage references are multipurpose, easy-to-use references that can be used in a vast array of applications. They feature low temperature drift, an initial accuracy of better than 0.1%, and fast settling time. Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V, the advanced design of the ADR5040/ADR5041/ADR5043/ ADR5044/ADR5045 eliminates the need for compensation by an external capacitor, yet the references are stable with any capacitive load. The minimum operating current increases from 50 µA to a maximum of 15 mA. This low operating current and ease of use make these references ideally suited for handheld, battery-powered applications. This family of references has been characterized over the extended temperature range of −40°C to +125°C. The ADR5041W and the ADR5044W are qualified for automotive applications and are available in a 3-lead SOT-23 package. Rev. C Table 1.

It is normalized by an output voltage of 25°C. This parameter is expressed in ppm/°C and is determined by the following equation: V (T ) − VOUT (T1 ) ppm × 10 6 = OUT 2 TCVOUT °C VO UT (25° C ) × (T2 − T1 ) where: VOUT(25°C) = VOUT at 25°C. VOUT(T1) = VOUT at Temperature 1. VOUT(T2) = VOUT at Temperature 2. (1) Thermal Hysteresis The change in output voltage after the device is cycled through temperatures ranging from +25°C to −40°C, then to +125°C, and back to +25°C. This is common in precision reference and is caused by thermal-mechanical package stress. Changes in environmental storage temperature, board mounting temperature, and the operating temperature are some of the factors that can contribute to thermal hysteresis. The following equation expresses a typical value from a sample of parts put through such a cycle: VOUT _ HYS = VOUT (25° C ) − VOUT _ TC VOUT _ HYS [ppm ] = VOUT (25° C ) − VOUT _ TC VOUT (25° C ) × 10 6 (2) where: VOUT(25°C) = VOUT at 25°C. VOUT_TC = VOUT at 25°C after a temperature cycle from +25°C to −40°C, then to +125°C, and back to +25°C. Rev.

The devices use the physical nature of a silicon transistor base-emitter voltage in the forwardbiased 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. Therefore, if a voltage develops with an opposing temperature coefficient to sum the VBE, a zero temperature coefficient reference results. Figure 19. Shunt Reference Precision Negative Voltage Reference The ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 are suitable for applications where a precise negative voltage is desired. Figure 20 shows the ADR5045 configured to provide a negative output. Exercise caution in using a low temperature sensitive resistor to avoid errors from the resistor. APPLICATIONS INFORMATION ADR5045 For a stable voltage, 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: RBIAS must be small enough to supply the minimum IIN current to the ADR5040/ADR5041/ADR5043/ADR5044/ADR5045, even when the supply voltage is at its minimum value and the load current is at its maximum value. RBIAS must be large enough so that IIN does not exceed 15 mA when the supply voltage is at its maximum value and the load current is at its minimum value. Given these conditions, RBIAS is determined by the supply voltage (VS), the ADR5040/ADR5041/ADR5043/ADR5044/ ADR5045 load and operating current (IL and IIN), and the ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 output voltage (VOUT).

Negative Precision Reference Configuration Stacking the ADR5040/ADR5041/ADR5043/ADR5044/ ADR5045 for User-Definable Outputs Multiple ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 devices can be stacked together to allow the user to obtain a desired higher voltage. Figure 21a shows three ADR5045 devices configured to give 15 V. The bias resistor, RBIAS, is chosen using Equation 3, noting that the same bias current flows through all the shunt references in series. Figure 21b shows three ADR5045 devices stacked together to give −15 V. RBIAS is calculated in the same manner as before. Parts of different voltages can also be added together; that is, an ADR5041 and an ADR5045 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 the sum of the errors of all the stacked parts, as are the temperature coefficient and output voltage change vs. input current.

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 remain stable.

C | Page 11 of 16 ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 Data Sheet Adjustable Precision Voltage Source Programmable Current Source The ADR5040/ADR5041/ADR5043/ADR5044/ADR5045, combined with a precision low input bias op amp such as the AD8610, can be used to output a precise adjustable voltage. Figure 22 illustrates the implementation of this application using the ADR5040/ADR5041/ADR5043/ADR5044/ADR5045. The output of the op amp, VOUT, is determined by the gain of the circuit, which is completely dependent on the resistors, R1 and R2. By using just a few ultrasmall and inexpensive parts, it is possible to build a programmable current source, as shown in Figure 23. The constant voltage on the gate of the transistor sets the current through the load. Varying the voltage on the gate changes the current. The AD5247 is a digital potentiometer with I2C® digital interface, and the AD8601 is a precision rail-to-rail input op amp. Each incremental step of the digital potentiometer increases or decreases the voltage at the noninverting input of the op amp. Therefore, this voltage varies with respect to the reference voltage. 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.
