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.
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.
The low current error of the LM108 makes possible many
designs that are not practical with conventional amplifiers. In
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.
Features
nMaximum input bias current of 3.0 nA over temperature
nOffset current less than 400 pA over temperature
nSupply current of only 300 µA, even in saturation
nGuaranteed drift characteristics

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 TJmax (maximum junction temperature), θJA (package
junction to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any temperature is PDmax=(T
Jmax - TA)/θJA
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.
Note 14: Calculated parameter for Class “S” only

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.
