LM124,LM224,LM2902,LM324 LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers Literature Number: SNOSC16B LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers General Description Advantages The LM124 series consists of four 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. n Eliminates need for dual supplies n Four internally compensated op amps in a single package n Allows directly sensing near GND and VOUT also goes to GND n Compatible with all forms of logic n Power drain suitable for battery operation 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 LM124 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 supplies. 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 Features n Internally frequency compensated for unity gain n Large DC voltage gain 100 dB n Wide bandwidth (unity gain) 1 MHz (temperature compensated) n Wide power supply range: Single supply 3V to 32V or dual supplies 1.5V to 16V n Very low supply current drain (700 A) -- essentially independent of supply voltage n Low input biasing current 45 nA (temperature compensated) n Low input offset voltage 2 mV and offset current: 5 nA n Input common-mode voltage range includes ground n Differential input voltage range equal to the power supply voltage n Large output voltage swing 0V to V+ - 1.5V Connection Diagrams Dual-In-Line Package 00929901 Top View Order Number LM124J, LM124AJ, LM124J/883 (Note 2), LM124AJ/883 (Note 1), LM224J, LM224AJ, LM324J, LM324M, LM324MX, LM324AM, LM324AMX, LM2902M, LM2902MX, LM324N, LM324AN, LM324MT, LM324MTX or LM2902N LM124AJRQML and LM124AJRQMLV(Note 3) See NS Package Number J14A, M14A or N14A (c) 2004 National Semiconductor Corporation DS009299 www.national.com LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers August 2000 LM124/LM224/LM324/LM2902 Connection Diagrams (Continued) 00929933 Order Number LM124AW/883, LM124AWG/883, LM124W/883 or LM124WG/883 LM124AWRQML and LM124AWRQMLV(Note 3) See NS Package Number W14B LM124AWGRQML and LM124AWGRQMLV(Note 3) See NS Package Number WG14A Note 1: LM124A available per JM38510/11006 Note 2: LM124 available per JM38510/11005 Note 3: See STD Mil DWG 5962R99504 for Radiation Tolerant Device Schematic Diagram (Each Amplifier) 00929902 www.national.com 2 If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ LM124/LM224/LM324 LM2902 LM124A/LM224A/LM324A Supply Voltage, V+ 32V 26V Differential Input Voltage 32V 26V -0.3V to +32V -0.3V to +26V 50 mA 50 mA Molded DIP 1130 mW 1130 mW Cavity DIP 1260 mW 1260 mW Small Outline Package 800 mW 800 mW Input Voltage Input Current (VIN < -0.3V) (Note 6) Power Dissipation (Note 4) Output Short-Circuit to GND (One Amplifier) (Note 5) V+ 15V and TA = 25C Continuous Continuous Operating Temperature Range -40C to +85C LM324/LM324A 0C to +70C LM224/LM224A -25C to +85C LM124/LM124A -55C to +125C Storage Temperature Range -65C to +150C -65C to +150C 260C 260C 260C 260C Vapor Phase (60 seconds) 215C 215C Infrared (15 seconds) 220C 220C Lead Temperature (Soldering, 10 seconds) Soldering Information Dual-In-Line Package Soldering (10 seconds) Small Outline Package See AN-450 "Surface Mounting Methods and Their Effect on Product Reliability" for other methods of soldering surface mount devices.

The LM224/LM224A and LM124/LM124A can be derated based on a +150C 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. 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 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 5 www.national.com LM124/LM224/LM324/LM2902 Electrical Characteristics LM124/LM224/LM324/LM2902 Electrical Characteristics (Continued) 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 25C). Note 7: These specifications are limited to -55C TA +125C for the LM124/LM124A. With the LM224/LM224A, all temperature specifications are limited to -25C TA +85C, the LM324/LM324A temperature specifications are limited to 0C TA +70C, and the LM2902 specifications are limited to -40C TA +85C. Note 8: VO . 1.4V, RS = 0 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 output so 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 25C). The upper end of the common-mode voltage range is V+ - 1.5V (at 25C), 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 typically can be detected as this type of capacitance increases at higher frequencies.

An input clamp diode with a resistor to the IC input terminal can be used. 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 VDC. These amplifiers operate over a wide range of power supply voltage with little change in performance characteristics. At 25C 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 www.national.com 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 noninverting unity gain connection. Large closed loop gains or resistive isolation should be used if larger load capacitance must be driven by the amplifier. 8 output source current which is available at 25C provides a larger output current capability at elevated temperatures (see typical performance characteristics) than a standard IC op amp. (Continued) 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 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 Typical Single-Supply Applications 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, 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.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
