For operating at high temperatures, the LM358 must be derated based on a +125°C maximum junction temperature and a thermal resistance of 189°C/W, which applies for the devi ce soldered in a printed circuit board, operating in a still air ambient. 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. 3. 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 40mA 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. 4. 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 t he 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 o utput states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3V (at 25°C).

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at25°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+. 9. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts.

Application Information

The LM358 series are op amps 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 0 V 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 2.3 V 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 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. The differential input voltage may be larger than V + without damaging the device. Protection should be provided to prevent the i nput voltages from going negative more than -0.3 V 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 sour ce 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 amp lifiers. 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 am plifier, 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 accommodated using the worst-case non- inverting unity gain connection. Large closed loop gains or resistive isolation should be used if a larger load capacitance must be driven by the amplifier. The bias network of the LM358 establishes a drain current which is independent of the magni tude of the power supply voltage over the range of 3 V DC to 30 VDC. Output short circuits either to ground or to the positive power supply should be of short time duration. Units can be destroyed, 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 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 protected with external dissipation limiting resistors in series with the output leads of the amplifiers. The larger valu e of output source current which is available at 25°C provides a larger output current capability at elevat ed 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 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.
