ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Its basic topology is shown in Figure 1. The transistors Q1 and Q2 are biased such that the current density of Q1 is greater than that of Q2. The difference of the two base-emitter voltages, Vbe1 – Vbe2, has a positive temperature coefficient and is forced across resistor R1. This voltage is gained up and added to the base-emitter voltage of Q2, which has a negative coefficient. The resulting output voltage is virtually independent of temperature. The curvature of the bandgap voltage, as seen in the typical curve, “Output Voltage vs Temperature,” is due to the slightly nonlinear temperature coefficient of the base-emitter voltage of Q2. The REF30xx features a low quiescent current, which is extremely stable over changes in both temperature and supply. The typical room temperature quiescent current is 42µA, and the maximum quiescent current over temperature is just 59µA. Additionally, the quiescent current typically changes less than 2.5µA over the entire supply range, as shown in Figure 3. Supply voltages below the specified levels can cause the REF30xx to momentarily draw currents greater than the typical quiescent current. Using a power supply with a fast rising edge and low output impedance easily prevents this.

Simplified Schematic of Bandgap Reference. THERMAL HYSTERESIS APPLICATION INFORMATION The REF30xx does not require a load capacitor, and is stable with any capacitive load. Figure 2 shows typical connections required for operation of the REF30xx. A supply bypass capacitor of 0.47µF is recommended. Thermal hysteresis for the REF30xx is defined as the change in output voltage after operating the device at 25°C, cycling the device through the specified temperature range, and returning to 25°C, and can be expressed as:  abs VPRE – VPOST  6 VHYST =   • 10 (ppm) VNOM   Where: VHYST = Calculated hysteresis VPRE = Output voltage measured at 25°C pretemperature cycling VIN 1 0.47µF REF30xx 3 VOUT 2 VPOST = Output voltage measured when device has been operated at 25°C, cycled through specified range –40°C to +125°C and returned to operation at 25°C. FIGURE 2. Typical Connections for Operating REF30xx. TEMPERATURE DRIFT The REF30xx is designed to exhibit minimal drift error, defined as the change in output voltage over varying temperature. Using the “box” method of drift measurement, the REF30xx features a typical drift coefficient of 20ppm from 0°C to 70°C— the primary temperature range of use for many applications. For industrial temperature ranges of –40°C to 125°C, the REF30xx family drift increases to a typical value of 50ppm. SUPPLY VOLTAGE The REF30xx family of references features an extremely low dropout voltage. With the exception of the REF3012, which has a minimum supply requirement of 1.8V, the REF30xx can be operated with a supply of only 1mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load is shown on the cover page. 8 REF3012, 3020, 3025, 3030, 3033, 3040 www.ti.com SBVS032E NOISE PERFORMANCE The REF30xx generates noise less than 50µVp-p between frequencies of 0.1Hz to 10Hz, and can be seen in the Typical Characteristic Curve “0.1 to 10Hz Voltage Noise.” The noise voltage of the REF30xx increases with output voltage and operating temperature. Additional filtering may be used to improve output noise levels, although care should be taken to ensure the output impedance does not degrade AC performance. LONG TERM STABILITY Long term stability refers to the change of the output voltage of a reference over a period of months or years. This effect lessens as time progresses as is apparent by the long term stability curves. The typical drift value for the REF30xx is 24ppm from 0-1000 hours, and 15ppm from 1000-2000 hours. This parameter is characterized by measuring 30 units at regular intervals for a period of 2000 hours. LOAD REGULATION Load regulation is defined as the change in output voltage due to changes in load current. Load regulation for the REF30xx is measured using force and sense contacts as pictured in Figure 4. The force and sense lines tied to the contact area of the output pin reduce the impact of contact and trace resistance, resulting in accurate measurement of the load regulation contributed solely by the REF30xx. For applications requiring improved load regulation, force and sense lines should be used. APPLICATION CIRCUITS Negative Reference Voltage For applications requiring a negative and positive reference voltage, the OPA703 and REF30xx can be used to provide a dual supply reference from a ±5V supply. Figure 5 shows the REF3025 used to provide a ±2.5V supply reference voltage. The low offset voltage and low drift of the OPA703 complement the low drift performance of the REF30xx to provide an accurate solution for split-supply applications. +5V REF3025 10kΩ +2.5V 10kΩ +5V OPA703 –2.5V –5V FIGURE 5.

DATA ACQUISITION Output Pin Contact and Trace Resistance + VOUT – Sense Line IL Force Line Load Meter Often data acquisition systems require stable voltage references to maintain necessary accuracy.
