FEATURES  
DESCRIPTION  
2
LOW TEMPERATURE DRIFT:  
High-Grade: 3ppm/°C (max)  
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.  
Standard-Grade: 8ppm/°C (max)  
HIGH ACCURACY:  
High-Grade: 0.05% (max)  
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.  
Standard-Grade: 0.1% (max)  
LOW NOISE: 3μVPP/V  
HIGH OUTPUT CURRENT: ±10mA  
TEMPERATURE RANGE: –40°C to +125°C  
Each reference voltage is available in both standard-  
and high-grade versions. They are offered in MSOP-8  
(available Q3, 2007) 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 21 shows a simplified block diagram of  
the REF50xx.  
SUPPLY VOLTAGE  
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.  
+VSUPPLY

REF50xx  
OUTPUT ADJUSTMENT (TRIM Pin)  
µT  
The REF50xx provides a very accurate voltage  
output. However, VOUT can be adjusted from the  
nominal value for the purpose of trimming system  
errors by configuring the TRIM pin (pin 5). The TRIM  
pin provides for adjustment of the voltage at VOUT  
over a ±15mV range. Figure 23 shows a typical circuit  
using the TRIM pin to adjust VOUT. When using this  
technique, the temperature coefficients of the  
resistors can degrade the temperature drift at the  
output.

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

TEMPERATURE MONITORING  
POWER DISSIPATION  
The temperature output terminal (TEMP, pin 3)  
provides a temperature-dependent voltage output  
with approximately 60ksource impedance. As seen  
in Figure 8, the output voltage follows the nominal  
relationship:  
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  
VTEMP PIN = 509mV + 2.64 × T(°C)  
Where:  
TJ = Junction temperature (°C)  
TA = Ambient temperature (°C)  
PD = Power dissipated (W)  
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.  
θJA  
= Junction-to-ambient thermal resistance  
(°C/W)  
The REF50xx junction temperature must not exceed  
the absolute maximum rating of +150°C.  
The TEMP pin has high output impedance (see  
Figure 21). 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 24.  
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.

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 26 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 25 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.

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)
