FEATURES
DESCRIPTION
2
•
Qualified for Automotive Applications
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.
•
Low Temperature Drift
–
–
High Grade: 3 ppm/°C (max)
Standard Grade: 8 ppm/°C (max)
Excellent temperature drift (3 ppm/°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 Accuracy
–
–
High Grade: 0.05% (max)
Standard Grade: 0.1% (max)
•
•
•
Low Noise: 3 µVPP/V
Each reference voltage is available in both standard-
and high-grade versions. They are offered in SO-8
packages and are specified from –40°C to 125°C.
High Output Current: ±10 mA
Temperature Range: –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 22 shows a simplified block diagram of
the REF50xx.
requirement of 2.7 V, these references can be
operated with a supply of 200 mV above the output
voltage in an unloaded condition. For loaded
conditions, a typical dropout voltage versus load plot
is shown in Figure 6 of Typical Characteristics.
VIN
USING THE TRIM/NR PIN
The REF50xx provides a very accurate voltage
output. However, VOUT can be adjusted to reduce
noise and shift the output voltage from the nominal
value by configuring the trim and noise reduction pin
(TRIM/NR, pin 5). The TRIM/NR pin provides a
±15-mV adjustment of the device bandgap, which

Figure 24 shows a typical circuit using the TRIM/NR
pin to adjust VOUT. When using this technique, the

BASIC CONNECTIONS
Figure 23 shows the typical connections for the
REF50xx.
A
supply bypass capacitor ranging
between 1 µF to 10 µF is recommended. A 1-µF to
50-µF, low-ESR output capacitor (CL) must be
connected from VOUT to GND. The ESR value should
be less than or equal to 1.5 Ω. The ESR minimizes
gain peaking of the internal 1.2-V reference and thus
reduces noise at the VOUT pin.
Figure 24. VOUT Adjustment Using 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 (as Figure 25 illustrates) in
combination with the internal 1-kΩ resistor creates a
low-pass filter that lowers the overall noise measured
on the VOUT pin. A capacitance of 1 µF is suggested
for a low-pass filter with a corner frequency of
14.5 Hz. Higher capacitance results in a lower cutoff
frequency.

TEMPERATURE DRIFT

The REF50xx is designed for minimal drift error,
which is defined as the change in output voltage over
REF50xx
temperature. The drift is calculated using the box

The REF50xx features a maximum drift coefficient of

for the standard-grade.

Figure 26. Buffering the TEMP Pin Output
TEMPERATURE MONITORING
The temperature output terminal (TEMP, pin 3)
provides a temperature-dependent voltage output
with approximately 60-kΩ source impedance. As
seen in Figure 8, the output voltage follows the
nominal relationship:
POWER DISSIPATION
The REF50xx family is specified to deliver current
loads of ±10 mA over the specified input voltage
range. The temperature of the device increases
according to the equation:
VTEMP PIN = 509 mV + 2.64 × T(°C)
TJ = TA + PD × θJA
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 79-mV change in voltage at the TEMP
pin.
Where:
TJ = Junction temperature (°C)
TA = Ambient temperature (°C)
PD = Power dissipated (W)
θJA
(°C/W)
= Junction-to-ambient thermal resistance
The REF50xx junction temperature must not exceed
the absolute maximum rating of 150°C.
The TEMP pin has high output impedance (see
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 26.
NOISE PERFORMANCE
Typical 0.1-Hz to 10-Hz 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.

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 28 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 5-V
supply. Figure 27 shows the REF5025 used to
provide a 2.5-V 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.

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.
