•
LOW TEMPERATURE DRIFT:  
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.  
–
–
High-Grade: 3ppm/°C (max)  
Standard-Grade: 8ppm/°C (max)  
•
HIGH ACCURACY:  
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.  
–
–
High-Grade: 0.05% (max)  
Standard-Grade: 0.1% (max)  
•
•
LOW NOISE: 3mVPP/V  
EXCELLENT LONG-TERM STABILITY:  
Each reference voltage is available in both standard-  
and high-grade versions. They are offered in MSOP-8  
and SO-8 packages, and are specified from –40°C to  
+125°C.

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.

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 28 shows a simplified block diagram of  
the REF50xx.  
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.

OUTPUT ADJUSTMENT USING THE TRIM/NR  
PIN  
REF50xx  
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 30 shows a typical circuit  
that allows an output adjustment of ±15mV

BASIC CONNECTIONS  
Figure 30. VOUT Adjustment Using the TRIM/NR  
Pin  
Figure 29 shows the typical connections for the  
REF50xx.  
A
supply bypass capacitor ranging  
between 1mF to 10mF is recommended. A 1mF to  
50mF 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.  
The REF50xx allows access to the bandgap through  
the TRIM/NR pin. Placing a capacitor from the  
TRIM/NR pin to GND (see Figure 31) in combination  
with the internal R3 and R4 resistors creates a  
low-pass filter. A capacitance of 1mF 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.

The REF50xx is designed for minimal drift error,  
which is defined as the change in output voltage over  
temperature. The drift is calculated using the box  
method, as described by the following equation:

OPA335, or OPA376, as shown in Figure 32.

THERMAL HYSTERESIS  
Thermal hysteresis for the REF50xx 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 Equation 2:  
Figure 32. Buffering the TEMP Pin Output  
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 × qJA

Where:  
Where:  
VHYST = thermal hysteresis (in units of ppm).  
VNOM = the specified output voltage.  
TJ = Junction temperature (°C)  
TA = Ambient temperature (°C)  
PD = Power dissipated (W)  
VPRE  
= output voltage measured at +25°C  
pretemperature cycling.  
qJA  
(°C/W)  
= Junction-to-ambient thermal resistance  
VPOST = output voltage measured after the device  
has been cycled from +25°C through the  
specified temperature range of –40°C to +125°C  
and returned to +25°C.  
The REF50xx junction temperature must not exceed  
the absolute maximum rating of +150°C.  
TEMPERATURE MONITORING  
NOISE PERFORMANCE  
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:  
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.  
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.  
For additional information about how to minimize  
noise and maximize performance in mixed-signal  
applications such as data converters, refer to the  
series of Analog Applications Journal articles entitled,  
How a Voltage Reference Affects ADC Performance.  
This three-part series is available for download from  
the TI website under three literature numbers:  
SLYT331, SLYT339, and SLYT355 for Part I, Part II,  
and Part III, respectively.  
The TEMP pin has high output impedance (see  
Figure 28). Loading this pin with a low-impedance  
circuit induces a measurement error; however, it does  
not have any effect on VOUT accuracy.

APPLICATION CIRCUITS  
DATA ACQUISITION  
NEGATIVE REFERENCE VOLTAGE  
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.  
Figure 34 shows the REF5040 in a basic data  
acquisition system.  
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 33 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.

(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.  
(4)  
Multiple Top-Side Markings will be inside parentheses. Only one Top-Side Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a  
continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
