overcompensated for increased stability margin. Or the
compensation can be optimized to give more than a
factor of ten improvement in high frequency performance
for most applications.
In addition, the device provides better accuracy and
lower noise in high impedance circuitry. The low input
currents also make it particularly well suited for long
interval integrators or timers, sample and hold circuits
and low frequency waveform generators. Further, replacing circuits where matched transistor pairs buffer the
inputs of conventional IC op amps, it can give lower offset
voltage and a drift at a lower cost.
General Description
The LM101A is a general purpose operational amplifier
which features improved performance over industry standards such as the LM709. Advanced processing techniques
make possible an order of magnitude reduction in input
currents, and a redesign of the biasing circuitry reduces the
temperature drift of input current. Improved specifications
include:
• Offset voltage 3 mV maximum over temperature
• Input current 100 nA maximum over temperature
• Offset current 20 nA maximum over temperature
• Guaranteed drift characteristics
• Offsets guaranteed over entire common mode and supply voltage ranges
• Slew rate of 10V/µs as a summing amplifier
This amplifier offers many features which make its application nearly foolproof: overload protection on the input
and output, no latch-up when the common mode range is
exceeded, and freedom from oscillations and compensation with a single 30 pF capacitor. It has advantages over
internally compensated amplifiers in that the frequency
compensation can be tailored to the particular application. For example, in low frequency circuits it can be

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is
intended to be functional, but do no 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 3: For supply voltages less than ± 15V, the absolute maximum input voltage is equal to the supply voltage.
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 = (TJmax − TA) / θJA or the
number given in the Absolute Maximum Ratings, whichever is lower.
Note 5: Human body model, 100 pF discharged through 1.5 kΩ.
Note 6: Parameter guaranteed by the input conditions of several DC parameters
Note 7: Parameter guaranteed, not tested.
Note 8: Calculated parameter
Note 9: Datalog reading of K = V/mV.
Note 10: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics. 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

Typical Applications
LM101AQML
Although the LM101A is designed for trouble free operation,
experience has indicated that it is wise to observe certain
precautions given below to protect the devices from abnormal operating conditions. It might be pointed out that the
advice given here is applicable to practically any IC op amp,
although the exact reason why may differ with different devices.
(Note 11)
Standard Compensation and
Offset Balancing Circuit
When driving either input from a low-impedance source, a
limiting resistor should be placed in series with the input lead
to limit the peak instantaneous output current of the source
to something less than 100 mA. This is especially important
when the inputs go outside a piece of equipment where they
could accidentally be connected to high voltage sources.
Large capacitors on the input (greater than 0.1 µF) should be
treated as a low source impedance and isolated with a
resistor. Low impedance sources do not cause a problem
unless their output voltage exceeds the supply voltage. However, the supplies go to zero when they are turned off, so the
isolation is usually needed.
The output circuitry is protected against damage from shorts
to ground. However, when the amplifier output is connected
to a test point, it should be isolated by a limiting resistor, as
test points frequently get shorted to bad places. Further,
when the amplifer drives a load external to the equipment, it
is also advisable to use some sort of limiting resistance to
preclude mishaps.
Precautions should be taken to insure that the power supplies for the integrated circuit never become
reversed — even under transient conditions. With reverse
voltages greater than 1V, the IC will conduct excessive current, fusing internal aluminum interconnects. If there is a
possibility of this happening, clamp diodes with a high peak
current rating should be installed on the supply lines. Reversal of the voltage between V+ and V− will always cause a
problem, although reversals with respect to ground may also
give difficulties in many circuits.
The minimum values given for the frequency compensation
capacitor are stable only for source resistances less than
10 kΩ, stray capacitances on the summing junction less than
5 pF and capacitive loads smaller than 100 pF. If any of
these conditions are not met, it becomes necessary to overcompensate the amplifier with a larger compensation capacitor. Alternately, lead capacitors can be used in the feedback
network to negate the effect of stray capacitance and large
feedback resistors or an RC network can be added to isolate
capacitive loads.
Although the LM101A is relatively unaffected by supply bypassing, this cannot be ignored altogether. Generally it is
necessary to bypass the supplies to ground at least once on
every circuit card, and more bypass points may be required
if more than five amplifiers are used. When feed-forward
compensation is employed, however, it is advisable to bypass the supply leads of each amplifier with low inductance
capacitors because of the higher frequencies involved.

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.
