LM4040xxx Precision Micropower Shunt Voltage Reference
1 Features
3 Description
•
The LM4040 series of shunt voltage references are
versatile, easy-to-use references that cater to a vast
array of applications. The 2-pin fixed-output device
requires no external capacitors for operation and is
stable with all capacitive loads. Additionally, the
reference offers low dynamic impedance, low noise,
and low temperature coefficient to ensure a stable
output voltage over a wide range of operating
currents and temperatures. The LM4040 uses fuse
and Zener-zap reverse breakdown voltage trim during
wafer sort to offer four output voltage tolerances,
ranging from 0.1% (max) for the A grade to 1% (max)
for the D grade. Thus, a great deal of flexibility is
offered to designers in choosing the best cost-toperformance ratio for their applications.

SLOS456M – JANUARY 2005 – REVISED JANUARY 2015
8 Detailed Description
8.1 Overview
The LM4040 is a precision micro-power curvature-corrected bandgap shunt voltage reference. The LM4040 has
been designed for stable operation without the need of an external capacitor connected between the “+” pin and
the “−” pin. If, however, a bypass capacitor is used, the LM4040 remains stable.
LM4040 offers several fixed reverse breakdown voltages: 2.048 V, 2.500 V, 3.000 V, 4.096 V, 5.000 V, 6.000,
8.192 V, and 10.000 V. The minimum operating current increases from 60 µA for the LM4040-N-2.048 and
LM4040-N-2.5 to 100 μA for the 10.0-V LM4040. All versions have a maximum operating current of 15 mA.
Each reverse voltage options can be purchased with initial tolerances (at 25°C) of 0.1%, 0.2%, 0.5% and 1.0%.
These reference options are denoted by A (0.1%), B (0.2%), C (0.5%) and D for (1.0%).
The LM4040xxxI devices are characterized for operation from –40°C to 85°C, and the LM4040xxxQ devices are
characterized for operation from –40°C to 125°C.

8.3 Feature Description
A temperature compensated band gap voltage reference controls high gain amplifier and shunt pass element to
maintain a nearly constant voltage between cathode and anode. Regulation occurs after a minimum current is
provided to power the voltage divider and amplifier. Internal frequency compensation provides a stable loop for
all capacitor loads. Floating shunt design is useful for both positive and negative regulation applications.
8.4 Device Functional Modes
8.4.1 Shunt Reference
LM4040x will operate in one mode, which is as a fixed voltage reference that cannot be adjusted. LM4040x does
offer various Reverse Voltage options that have unique electrical characteristics detailed in the Specifications
section.
In order for a proper Reverse Voltage to be developed, current must be sourced into the cathode of LM4040x.
The minimum current needed for proper regulation is denoted in the Specifications section as IZ,min.

9 Applications and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
LM4040xxx is a well known industry standard device used in several applications and end equipment where a
reference is required. Below describes this device being used in a data acquisition system. Analog to Digital
conversion systems are the most common applications to use LM4040x due to its low reference tolerance which
allows high precision in these systems.

9.2.2 Detailed Design Procedure
When using LM4040x as a comparator with reference, determine the following:
• Input voltage range
• Reference voltage accuracy
• Output logic input high and low level thresholds
• Current source resistance
9.2.2.1 LM4040x Voltage and Accuracy Choice
When using LM4040x as a reference for an ADC, the ADC's FSR (Full Scale Range), Resolution and LSB must
be determined. LSB can be determined by:
LSB=FSR/(2N-1)
With N being the resolution or Number of Bits. FSR and Resolution can be determined by the ADC's datasheet.
Vref can be determined by:
Vref=FSR+LSB
Though modern data converters use calibration techniques to compensate for any error introduced by a Vref's
inaccuracy, it is best to use the highest accuracy available. This is due to errors in the calibration method that
may allow some non-linearities introduced by the Vref's initial accuracy.
A good example is the LM4040x-41 that is designed to be a cost-effective voltage reference as required in 12-bit
data-acquisition systems. For 12-bit systems operating from 5-V supplies (see Figure 6), the LM4040A-41 (4.096
V, 0.01%) only introduces 4 LSBs (4mV) of possible error in a system that consists of 4096 LSBs.
9.2.2.2 Cathode and Load Currents
In a typical shunt-regulator configuration (see Figure 7), an external resistor, RS, is connected between the
supply and the cathode of the LM4040. RS must be set properly, as it sets the total current available to supply
the load (IL) and bias the LM4040 (IZ). In all cases, IZ must stay within a specified range for proper operation of
the reference. Taking into consideration one extreme in the variation of the load and supply voltage (maximum IL
and minimum VS), RS must be small enough to supply the minimum IZ required for operation of the regulator, as
given by data-sheet parameters. At the other extreme, maximum VS and minimum IL, RS must be large enough
to limit IZ to less than its maximum-rated value of 15 mA.
RS is calculated according to Equation 1:
(V - VZ )
RS = S
(IL + IZ )

9.2.2.3 Output Capacitor
The LM4040 does not require an output capacitor across cathode and anode for stability. However, if an output
bypass capacitor is desired, the LM4040 is designed to be stable with all capacitive loads.

9.2.2.4 SOT-23 Connections
There is a parasitic Schottky diode connected between pins 2 and 3 of the SOT-23 packaged device. Thus, pin 3
of the SOT-23 package must be left floating or connected to pin 2.
9.2.2.5 Start-Up Characteristics
In any data conversion system, start-up characteristics are important, as to determine when it is safe begin
conversion based upon a steady and settled reference value. As shown in Figure 9 it is best to allow for >20µs
from supply start-up to begin conversion.

10 Power Supply Recommendations
In order to not exceed the maximum cathode current, be sure that the supply voltage is current limited.
For applications shunting high currents (15 mA max), pay attention to the cathode and anode trace lengths,
adjusting the width of the traces to have the proper current density.

• Connect a low-ESR, 0.1-μF (CL) ceramic bypass capacitor on the cathode pin node.
• Decouple other active devices in the system per the device specifications.
• Using a solid ground plane helps distribute heat and reduces electromagnetic interference (EMI) noise pickup.
• Place the external components as close to the device as possible. This configuration prevents parasitic errors
(such as the Seebeck effect) from occurring.
• Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if
possible and only make perpendicular crossings when absolutely necessary.

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)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device 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 Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

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.
