FEATURES

DESCRIPTION

•

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: 3μV_PP/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

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.

+V_SUPPLY

V_IN

REF50xx

OUTPUT ADJUSTMENT (TRIM Pin)

µT

The REF50xx provides a very accurate voltage

output. However, V_OUTcan 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 V_OUT

over a ±15mV range. Figure 23 shows a typical circuit

using the TRIM pin to adjust V_OUT. When using this

technique, the temperature coefficients of the

resistors can degrade the temperature drift at the

output.

TEMPERATURE MONITORING

POWER DISSIPATION

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:

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:

T_J= T_A+ P_D× θ_JA

V_{TEMP PIN}= 509mV + 2.64 × T(°C)

Where:

T_J= Junction temperature (°C)

T_A= Ambient temperature (°C)

P_D= 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.

θ_JA

= 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 V_OUTaccuracy. 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 R₁and 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)
