The LM224/LM224A and LM124/LM124A can be de- rated based on a +150˚C maximum junction temperature. The dissipation is the total of all four amplifiers — use external resistors, where possible, toallow the am- plifier to saturate of to reduce the power which is dissipated in the integrated circuit. Note 5: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 6: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 PNPtran- sistors 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 7:These specifications are limited to −55˚C≤ TA ≤ +125˚C for the LM124/LM124A. With the LM224/LM224A, all temperature specifications are limited to −25˚C ≤ TA ≤ +85˚C, the LM324/LM324A temperature specifications are limited to 0˚C≤ TA ≤ +70˚C, and the LM2902 specifications are limited to −40˚C≤ TA ≤ +85˚C. Note 8:VO .1.4V, RS =0 Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ − 1.5V) for LM2902, V+ from 5V to 26V. Note 9: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 outputs o no loading change exists on the input lines. Note 10: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 (+26V for LM2902), independent of the magnitude of V+. Note 11:Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typicallycan be detected as this type of capacitance increases at higher frequencies.

Typical Performance Characteristics(Continued) Application Hints The LM124 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 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 . The pinouts of the package have been designed to simplify PC board layouts. Inverting inputs are adjacent to outputs for all of the amplifiers and the outputs have also been placed at the corners of the package (pins 1, 7, 8, and 14). 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 in- ternal conductors and result in a destroyed unit. Large differential input voltages can be easily accommo- dated and, as input differential voltage protection diodes are not needed, no large input currents result from large differen- tial 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 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 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 capaci- tance must be driven by the amplifier. The bias network of the LM124 establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 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 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 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 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.
