LM158QML
Low Power Dual Operational Amplifiers
General Description
The LM158 series consists of two independent, high gain, in-
ternally frequency compensated operational amplifiers which
were designed specifically to operate from a single power
supply over a wide range of voltages. Operation from split
power supplies is also possible and the low power supply
current drain is independent of the magnitude of the power
supply voltage.
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which now can
be more easily implemented in single power supply systems.
For example, the LM158 series can be directly operated off
of the standard +5V power supply voltage which is used in
digital systems and will easily provide the required interface
electronics without requiring the additional ±15V power sup-
plies.
Unique Characteristics
In the linear mode the input common-mode voltage range
includes ground and the output voltage can also swing to
ground, even though operated from only a single power
supply voltage.
The unity gain cross frequency is temperature
compensated.
The input bias current is also temperature compensated.

Note 2: 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 3: 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 4: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output
current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short-circuits can exceed the
power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
Note 5: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action
on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V+voltage level (or to ground for a large overdrive) for the time
duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again
returns to a value greater than −0.3V (at 25°C).
Note 6: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output
so no loading change exists on the input lines.
Note 7: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of the
common-mode voltage range is V+ −1.5V (at 25°C), but either or both inputs can go to +32V without damage, independent of the magnitude of V+.
Note 8: Human body model, 1.5 kΩ in series with 100 pF.
Note 9: Guaranteed by input offset voltage.
Note 10: Guaranteed parameter not tested.
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 sensitivity. Radiation end point limits for the noted
parameters are guaranteed only for the conditions as specified in MIL-STD-883, per Test Method 1019, Condition A.
Note 12: 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 sensitive in a high dose environment. Low dose rate testing has been performed on a wafer-by-wafer basis, per Test Method 1019, Condition
D of MIL-STD-883, with no enhanced low dose rate sensitivity (ELDRS).

Application Hints
The LM158 series are op amps which operate with only a
single power supply voltage, have true-differential inputs, and
remain in the linear mode with an input common-mode volt-
age of 0 VDC. These amplifiers operate over a wide range of
power supply voltage with little change in performance char-
acteristics. At 25°C amplifier operation is possible down to a
minimum supply voltage of 2.3 VDC.
Precautions should be taken to insure that the power supply
for the integrated circuit never becomes reversed in polarity
or that the unit is not inadvertently installed backwards in a
test socket as an unlimited current surge through the resulting
forward diode within the IC could cause fusing of the internal
conductors and result in a destroyed unit.
Large differential input voltages can be easily accommodated
and, as input differential voltage protection diodes are not
needed, no large input currents result from large differential
input voltages. The differential input voltage may be larger
than V+ without damaging the device. Protection should be
provided to prevent the input voltages from going negative
more than −0.3 VDC (at 25°C). An input clamp diode with a
resistor to the IC input terminal can be used.
To reduce the power supply current drain, the amplifiers have
a class A output stage for small signal levels which converts
to class B in a large signal mode. This allows the amplifiers
to both source and sink large output currents. Therefore both
NPN and PNP external current boost transistors can be used
to extend the power capability of the basic amplifiers. The
output voltage needs to raise approximately 1 diode drop
above ground to bias the on-chip vertical PNP transistor for
output current sinking applications.
For ac applications, where the load is capacitively coupled to
the output of the amplifier, a resistor should be used, from the
output of the amplifier to ground to increase the class A bias
current and prevent crossover distortion. Where the load is
directly coupled, as in dc applications, there is no crossover
distortion.
Capacitive loads which are applied directly to the output of the
amplifier reduce the loop stability margin. Values of 50 pF can
be accommodated using the worst-case non-inverting unity
gain connection. Large closed loop gains or resistive isolation
should be used if larger load capacitance must be driven by
the amplifier.
The bias network of the LM158 establishes a drain current
which is independent of the magnitude of the power supply
voltage over the range of 3 VDC to 30 VDC.
Output short circuits either to ground or to the positive power
supply should be of short time duration. Units can be de-
stroyed, not as a result of the short circuit current causing
metal fusing, but rather due to the large increase in IC chip
dissipation which will cause eventual failure due to excessive
junction temperatures. Putting direct short-circuits on more
than one amplifier at a time will increase the total IC power
dissipation to destructive levels, if not properly protected with
external dissipation limiting resistors in series with the output
leads of the amplifiers. The larger value of output source cur-
rent which is available at 25°C provides a larger output current
capability at elevated temperatures (see typical performance
characteristics) than a standard IC op amp.
The circuits presented in the section on typical applications
emphasize operation on only a single power supply voltage.
If complementary power supplies are available, all of the stan-
dard op amp circuits can be used. In general, introducing a
pseudo-ground (a bias voltage reference of V+/2) will allow
operation above and below this value in single power supply
systems. Many application circuits are shown which take ad-
vantage of the wide input common-mode voltage range which
includes ground. In most cases, input biasing is not required
and input voltages which range to ground can easily be ac-
commodated.
