LM108/LM108AQML  
Operational Amplifiers  
General Description  
The LM108 is a precision operational amplifier having speci-  
fications a factor of ten better than FET amplifiers over a  
−55˚C to +125˚C temperature range.  
fact, it operates from 10 Msource resistances, introducing  
less error than devices like the 709 with 10 ksources.  
Integrators with drifts less than 500 µV/sec and analog time  
delays in excess of one hour can be made using capacitors  
no larger than 1 µF.  
The devices operate with supply voltages from 2V to 20V  
and have sufficient supply rejection to use unregulated sup-  
plies. Although the circuit is interchangeable with, and uses  
the same compensation as the LM101A, an alternate com-  
pensation scheme can be used to make it particularly insen-  
sitive to power supply noise and to make supply bypass  
capacitors unnecessary.  
Features  
n Maximum input bias current of 3.0 nA over temperature  
n Offset current less than 400 pA over temperature  
n Supply current of only 300 µA, even in saturation  
n Guaranteed drift characteristics  
The low current error of the LM108 makes possible many  
designs that are not practical with conventional amplifiers. In

Note 2: Parameters have only been entered in the LM108 / LM108A column if different from LM108RH  
Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is  
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed  
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test  
conditions.  
Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by T max (maximum junction temperature), θ (package  
J

junction to ambient thermal resistance), and T (ambient temperature). The maximum allowable power dissipation at any temperature is P max = (T max - T ) /θ

or the number given in the Absolute Maximum Ratings, whichever is lower.  
Note 5: The inputs are shunted with back-to-back diodes for over voltage protection. Therefore, excessive current will flow if a differential input voltage in excess  
of 1V is applied between the inputs unless some limiting resistance is used.  
Note 6: For supply voltages less than 20V, the absolute maximum input voltage is equal to the supply voltage.  
Note 7: This rating is 1.0V unless resistances of 2K Ohms or greater are inserted in series with the inputs to limit current in the input shunt diodes to the maximum  
allowable value..  
Note 8: Human body model, 1.5 kin series with 100 pF.  
Note 9: Calculated parameter  
Note 10: Datalog reading in K = V/mV  
Note 11: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics except as listed in the Post Radiation Limits Table.  
These parts may be dose rate sensitive in a space environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters  
are guaranteed only for the conditions as specified in MIL-STD-883, Method 1019.5.  
Note 12: Parameter tested Go-No-Go  
Note 13: Guaranteed parameter not tested.

LIFE SUPPORT POLICY  
NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS  
WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR  
CORPORATION. As used herein:  
1. Life support devices or systems are devices or systems  
which, (a) are intended for surgical implant into the body, or  
(b) support or sustain life, and whose failure to perform when  
properly used in accordance with instructions for use  
provided in the labeling, can be reasonably expected to result  
in a significant injury to the user.  
2. A critical component is any component of a life support  
device or system whose failure to perform can be reasonably  
expected to cause the failure of the life support device or  
system, or to affect its safety or effectiveness.  
BANNED SUBSTANCE COMPLIANCE  
National Semiconductor manufactures products and uses packing materials that meet the provisions of the Customer Products  
Stewardship Specification (CSP-9-111C2) and the Banned Substances and Materials of Interest Specification (CSP-9-111S2) and contain  
no ‘‘Banned Substances’’ as defined in CSP-9-111S2.  
Leadfree products are RoHS compliant.

sold subject to TIs terms and conditions of sale supplied at the time of order acknowledgment.  
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TIs standard  
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
mandated by government requirements, testing of all parameters of each product is not necessarily performed.  
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,  
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive  
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional  
restrictions.  
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all  
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
