LM158/LM258/LM358/LM2904

Low Power Dual Operational Amplifiers

General Description

The LM158series consists of two independent,high gain,internally 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 LM158series 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 supplies.

The LM358and LM2904are available in a chip sized pack-age (8-Bump micro SMD)using National’s micro SMD pack-age technology.

Unique Characteristics

n 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.

n The unity gain cross frequency is temperature compensated.

n The input bias current is also temperature compensated.

Advantages

Note1:For operating at high temperatures,the LM358/LM358A,LM2904must be derated based on a+125?C maximum junction temperature and a thermal resistance of120?C/W for MDIP,182?C/W for Metal Can,189?C/W for Small Outline package,and230?C/W for micro SMD,which applies for the device soldered in a printed circuit board,operating in a still air ambient.The LM258/LM258A and LM158/LM158A can be derated based on a+150?C maximum junction temperature.

The dissipation is the total of both amplifiers—use external resistors,where possible,to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit.

Note2:Short circuits from the output to V+can cause excessive heating and eventual destruction.When considering short cirucits to ground,the maximum output current is approximately40mA 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.

Note3: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(at25?C).

Note4:These specifications are limited to?55?C≤T A≤+125?C for the LM158/LM158A.With the LM258/LM258A,all temperature specifications are limited to

?25?C≤T A≤+85?C,the LM358/LM358A temperature specifications are limited to0?C≤T A≤+70?C,and the LM2904specifications are limited to?40?C≤T A≤+85?C.

Note5:V O.1.4V,R S=0?with V+from5V to30V;and over the full input common-mode range(0V to V+?1.5V)at25?C.For LM2904,V+from5V to26V.

Note6: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.

Note7:The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than0.3V(at25?C).The upper end of the common-mode voltage range is V+?1.5V(at25?C),but either or both inputs can go to+32V without damage(+26V for LM2904),independent of the magnitude of V+.

Note8:Due to proximity of external components,insure that coupling is not originating via stray capacitance between these external parts.This typically can be detected as this type of capacitance increases at higher frequencies.

Note9:Refer to RETS158AX for LM158A military specifications and to RETS158X for LM158military specifications.

Application Hints

The LM158series 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 voltage of 0V DC .These amplifiers operate over a wide range of power supply voltage with little change in performance characteristics.At 25?C amplifier operation is possible down to a minimum supply voltage of 2.3V DC .

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 result-ing 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 accomodated 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 ?0.3V DC (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 transis-tors can be used to extend the power capability of the basic amplifiers.The output voltage needs to raise approximately 1diode 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 50pF can be accomodated using the worst-case non-inverting unity gain https://www.wendangku.net/doc/a56379199.html,rge closed loop gains or resistive isolation should be used if larger load capacitance must be driven by the amplifier.

The bias network of the LM158establishes a drain current which is independent of the magnitude of the power supply voltage over the range of 3V DC to 30V DC .

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 exces-sive function 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 pro-tected with external dissipation limiting resistors in series with the output leads of the amplifiers.The larger value of output source current 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 standard op amp circuits can be used.In general,introduc-ing 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 advantage 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 accommodated.
