SBOS410C – JUNE 2007 – REVISED DECEMBER 2008 Low-Noise, Very Low Drift, Precision VOLTAGE REFERENCE FEATURES DESCRIPTION 1 • LOW TEMPERATURE DRIFT: – High-Grade: 3ppm/°C (max) – Standard-Grade: 8ppm/°C (max) • HIGH ACCURACY: – High-Grade: 0.05% (max) – Standard-Grade: 0.1% (max) • LOW NOISE: 3µVPP/V • HIGH OUTPUT CURRENT: ±10mA • TEMPERATURE RANGE: –40°C to +125°C The REF50xx is a family of low-noise, low-drift, very high precision voltage references. These references are capable of both sinking and sourcing, and are very robust with regard to line and load changes. 2 Excellent temperature drift (3ppm/°C) and high accuracy (0.05%) are achieved using proprietary design techniques. These features, combined with very-low noise make the REF50xx family ideal for use in high-precision data acquisition systems. Each reference voltage is available in both standardand high-grade versions. They are offered in MSOP-8(3) and SO-8 packages, and are specified from –40°C to +125°C.

SBOS410C – JUNE 2007 – REVISED DECEMBER 2008 APPLICATION INFORMATION The REF50xx is family of low-noise, precision bandgap voltage references that are specifically designed for excellent initial voltage accuracy and drift. Figure 21 shows a simplified block diagram of the REF50xx. VIN REF50xx R2 OUTPUT ADJUSTMENT USING THE TRIM/NR PIN (10mA at +25°C) VOUT R4 10kW R3 TRIM/NR R5 60kW The REF50xx family of voltage references features extremely low dropout voltage. With the exception of the REF5020, which has a minimum supply requirement of 2.7V, these references can be operated with a supply of 200mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load plot is shown in Figure 6 of the Typical Characteristics. R1 aT TEMP aT SUPPLY VOLTAGE 1.2V 1kW The REF50xx provides a very accurate, factory-trimmed voltage output. However, VOUT can be adjusted using the trim and noise reduction pin (TRIM/NR, pin 5). Figure 23 shows a typical circuit that allows an output adjustment of ±15mV +VSUPPLY GND REF50xx DNC Figure 21. REF50xx Simplified Block Diagram VIN TEMP +VSUPPLY REF50xx CBYPASS 1mF to 10mF TEMP 10kW 470kW Figure 22 shows the typical connections for the REF50xx. A supply bypass capacitor ranging between 1µF to 10µF is recommended. A 1µF to 50µF output capacitor (CL) must be connected from VOUT to GND. The ESR value of CL must be less than or equal to 1.5Ω to ensure output stability. To minimize noise, the recommended ESR of CL is between 1Ω and 1.5Ω. VIN NC VOUT GND TRIM/NR BASIC CONNECTIONS DNC DNC DNC NC VOUT GND TRIM/NR VOUT CL 1mF to 50mF 1kW Figure 23. VOUT Adjustment Using the TRIM/NR Pin The REF50xx allows access to the bandgap through the TRIM/NR pin. Placing a capacitor from the TRIM/NR pin to GND (see Figure 24) in combination with the internal R3 and R4 resistors creates a low-pass filter. A capacitance of 1µF creates a low-pass filter with the corner frequency between 10Hz and 20Hz. Such a filter decreases the overall noise measured on the VOUT pin by half. Higher capacitance results in a lower filter cutoff frequency, further reducing output noise. Note that use of this capacitor increases startup time. Figure 22.

Loading this pin with a low-impedance circuit induces a measurement error; however, it does not have any effect on VOUT accuracy. To avoid errors caused by low-impedance loading, buffer the TEMP pin output with a suitable low-temperature drift op amp, such as the OPA333, OPA335, or OPA376, as shown in Figure 25. +VSUPPLY REF50xx DNC DNC VIN TEMP NC VOUT GND TRIM/NR C1 1mF +V Figure 24. Noise Reduction Using the TRIM/NR Pin VTEMP 2.6mV/°C TEMPERATURE DRIFT The REF50xx is designed for minimal drift error, which is defined as the change in output voltage over temperature.

Figure 25. Buffering the TEMP Pin Output 106(ppm) (1) The REF50xx features a maximum drift coefficient of 3ppm/°C for the high-grade version, and 8ppm/°C for the standard-grade. POWER DISSIPATION The REF50xx family is specified to deliver current loads of ±10mA over the specified input voltage range. The temperature of the device increases according to the equation: TJ = TA + PD × θJA TEMPERATURE MONITORING The temperature output terminal (TEMP, pin 3) provides a temperature-dependent voltage output with approximately 60kΩ source impedance. As seen in Figure 8, the output voltage follows the nominal relationship: VTEMP PIN = 509mV + 2.64 × T(°C) This pin indicates general chip temperature, accurate to approximately ±15°C. Although it is not generally suitable for accurate temperature measurements, it can be used to indicate temperature changes or for temperature compensation of analog circuitry. A temperature change of 30°C corresponds to an approximate 79mV change in voltage at the TEMP pin. 10 Submit Documentation Feedback Where: TJ = Junction temperature (°C) TA = Ambient temperature (°C) PD = Power dissipated (W) θJA = Junction-to-ambient thermal resistance (°C/W) The REF50xx junction temperature must not exceed the absolute maximum rating of +150°C. NOISE PERFORMANCE Typical 0.1Hz to 10Hz voltage noise for each member of the REF50xx family is specified in the Electrical Characteristics: Per Device table. The noise voltage 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 performance.

SBOS410C – JUNE 2007 – REVISED DECEMBER 2008 APPLICATION CIRCUITS NEGATIVE REFERENCE VOLTAGE DATA ACQUISITION For applications requiring a negative and positive reference voltage, the REF50xx and OPA735 can be used to provide a dual-supply reference from a 5V supply. Figure 26 shows the REF5025 used to provide a 2.5V supply reference voltage. The low drift performance of the REF50xx 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. Data acquisition systems often require stable voltage references to maintain accuracy. The REF50xx family features low noise, very low drift, and high initial accuracy for high-performance data converters.

(3) (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
