The small size and low power consumption (120µA max) of the REF32xx make it ideal for portable and battery-powered applications. This reference is stable with any capacitive load. The REF32xx can be operated from a supply as low as 5mV above the output voltage, under no load conditions. All models are specified for the wide temperature range of −40°C to +125°C.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. 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.

Figure 1 shows the basic bandgap topology. Transistors Q1 and Q2 are biased so 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 amplified and added to the base-emitter voltage of Q2, which has a negative temperature coefficient. The resulting output voltage is virtually independent of temperature. APPLICATION INFORMATION The REF32xx does not require a load capacitor and is stable with any capacitive load. Figure 2 shows typical connections required for operation of the REF32xx. A supply bypass capacitor of 0.47µF is recommended. 1 0.47µ F +5V 6 +2.5V R32C 2 3 5 4 VBANDGAP Figure 2. Typical Operating Connections for the REF3225 R1 + Vbe1 − + Vbe2 − SUPPLY VOLTAGE The REF32xx family of references features an extremely low dropout voltage. With the exception of the REF3212, which has a minimum supply requirement of 1.8V, these references can be operated with a supply of only 5mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load is shown in the Typical Characteristic curves. Q1 I N Q2 Figure 1. Simplified Schematic of Bandgap Reference 8 www.ti.com REF3212, REF3220 REF3225, REF3230 REF3233, REF3240 SBVS058B −JUNE 2005 − REVISED FEBRUARY 2006 The REF32xx also features a low quiescent current of 100µA, with a maximum quiescent current over temperature of just 135µA. The quiescent current typically changes less than 2µA over the entire supply range, as shown in Figure 3. THERMAL HYSTERESIS Thermal hysteresis for the REF32xx 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. It can be expressed as: 110 108 Quiescent Current (µA) 106 104 102 100 98 96 94 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 Power Supply (V) V HYST + Where: VPRE * VPOST VNOM 106(ppm) (1) VHYST = thermal hysteresis (in units of ppm). VNOM = the specified output voltage. VPRE = output voltage measured at +25_C pretemperature cycling. VPOST = output voltage measured after the device has been cycled through the specified temperature range of –40_C to +125_C and returned to +25_C. TEMPERATURE DRIFT Figure 3. Supply Current vs Supply Voltage Supply voltages below the specified levels can cause the REF32xx to momentarily draw currents greater than the typical quiescent current. This momentary current draw can be prevented by using a power supply with a fast rising edge and low output impedance. The REF32xx is designed to exhibit minimal drift error, which is defined as the change in output voltage over varying temperature. The drift is calculated using the box method, as described by the following equation: Drift + V OUTMAX * V OUTMIN V OUT Temp Range 106(ppm) (2) SHUTDOWN The REF32xx can be placed in a low-power mode by pulling the ENABLE/SHUTDOWN pin low. When in Shutdown mode, the output of the REF32xx becomes a resistive load to ground. The value of the load depends on the model, and ranges from approximately 100kΩ to 400kΩ. The REF32xx features a typical drift coefficient of 4ppm/°C from 0_C to +125_C—the primary temperature range for many applications. For the extended industrial temperature range of –40_C to +125_C, the REF32xx family drift increases to a typical value of 10.5ppm/°C. NOISE PERFORMANCE Typical 0.1Hz to 10Hz voltage noise can be seen in the Typical Characteristic curve, 0.1 to 10Hz Voltage Noise. The noise voltage of the REF32xx increases with output voltage and operating temperature. Additional filtering can be used to improve output noise levels, although care should be taken to ensure the output impedance does not degrade AC performance. 9 REF3212, REF3220 REF3225, REF3230 REF3233, REF3240 SBVS058B −JUNE 2005 − REVISED FEBRUARY 2006 www.ti.com 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 shown by the long-term stability Typical Characteristic curves. The typical drift value for the REF32xx is 55ppm from 0 to 1000 hours. This parameter is characterized by measuring 30 units at regular intervals for a period of 1000 hours. APPLICATION CIRCUITS NEGATIVE REFERENCE VOLTAGE For applications requiring a negative and positive reference voltage, the REF32xx and OPA735 can be used to provide a dual-supply reference from a ±5V supply. Figure 5 shows the REF3225 used to provide a ±2.5V supply reference voltage. The low drift performance of the REF32xx complements the low offset voltage and zero drift of the OPA735 to provide an accurate solution for split-supply applications. Care must be taken to match the temperature coefficients of R1 and R2. LOAD REGULATION Load regulation is defined as the change in output voltage as a result of changes in load current. The load regulation of the REF32xx is measured using force and sense contacts, as shown in Figure 4. The force and sense lines can be used to effectively eliminate the impact of contact and trace resistance, resulting in accurate voltage at the load. By connecting the force and sense lines at the load, the REF32xx compensates for the contact and trace resistances because it measures and adjusts the voltage actually delivered at the load. +5V 3 4 5 6 REF3225 2 1 +2.5V R1 10kΩ R2 10kΩ Contact and Trace Resistance +5V OPA735 − 2.5V GND_F 1 REF32xx 6 OUT_F − 5V NOTE: Bypass capacitor is not shown.
