(3) 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).

(4) For operating at high temperatures, the LM324-N/LM324A/LM2902-N must be derated based on a +125°C maximum junction

temperature and a thermal resistance of 88°C/W which applies for the device soldered in a printed circuit board, operating in a still air

ambient. The LM224-N/LM224A and LM124-N/LM124A can be derated based on a +150°C maximum junction temperature. The

dissipation is the total of all four amplifiers—use external resistors, where possible, to allow the amplifier to saturate of to reduce the

power which is dissipated in the integrated circuit.

(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.

APPLICATION HINTS

The LM124-N 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 VDC. 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 VDC.

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 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 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 LM124-N establishes a drain current which is independent of the magnitude of the power

supply voltage over the range of from 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 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 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 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 Single-Supply 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, 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.

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between

the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight

in homogeneous material)

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other

changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest

issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and

complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale

supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which

anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use

of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to

help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and

requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties

have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in

military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components

which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and

regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of

non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
