LM124AQML LM124AQML LM124QML Low Power Quad Operational Amplifiers Literature Number: SNOSAE0J Low Power Quad Operational Amplifiers General Description Advantages The LM124/124A 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. 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 LM124/124A can be directly operated off of the standard +5Vdc power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional +15Vdc power supplies. Eliminates need for dual supplies Four internally compensated op amps in a single package Allows directly sensing near GND and VOUT also goes to Unique Characteristics 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 The unity gain cross frequency is temperature compensated The input bias current is also temperature compensated GND Compatible with all forms of logic Power drain suitable for battery operation Features Available with Radiation Guarantee 100 krad(Si) -- High Dose Rate 100 krad(Si) -- ELDRS Free Internally frequency compensated for unity gain Large DC voltage gain 100 dB Wide bandwidth (unity gain) 1 MHz (temperature compensated) Wide power supply range: Single supply 3V to 32V or dual supplies 1.5V to 16V Very low supply current drain (700 A)--essentially independent of supply voltage Low input biasing current 45 nA (temperature compensated) Low input offset voltage 2 mV and offset current: 5 nA Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Large output voltage swing 0V to V+ - 1.5V Ordering Information SMD Part Number NS Package Number LM124J/883 7704301CA J14A 14LD CERDIP LM124AE/883 77043022A E20A 20LD LEADLESS CHIP CARRIER LM124AJ/883 7704302CA J14A 14LD CERDIP W14B 14LD CERPACK NS Part Number LM124AW/883 LM124AWG/883 Package Description 7704302XA WG14A LM124AJRQMLV (Note 11) 5962R9950401VCA, 100 krad(Si) J14A 14LD CERDIP LM124AJRLQMLV (Note 12) 5962R9950402VCA, 100 krad(Si) J14A 14LD CERDIP LM124AWGRQMLV (Note 11) 5962R9950401VZA, 100 krad(Si) WG14A 14LD CERAMIC SOIC LM124AWGRLQMLV (Note 12) 5962R9950402VZA, 100 krad(Si) WG14A 14LD CERAMIC SOIC LM124AWRQMLV (Note 11) 5962R9950401VDA, 100 krad(Si) W14B 14LD CERPACK LM124AWRLQMLV (Note 12) 5962R9950402VDA, 100 krad(Si) W14B 14LD CERPACK LM124 MDE (Note 12) 5962R9950402V9A, 100 krad(Si) (Note 1) Bare Die LM124 MDR (Note 11) 5962R9950401V9A, 100 krad(Si) (Note 1) Bare Die (c) 2011 National Semiconductor Corporation 201080 14LD CERAMIC SOIC www.national.com LM124AQML/LM124QML Low Power Quad Operational Amplifiers October 12, 2010 LM124AQML LM124QML LM124AQML/LM124QML Note 1: FOR ADDITIONAL DIE INFORMATION, PLEASE VISIT THE HI REL WEB SITE AT: www.national.com/analog/space/level_die Connection Diagrams Leadless Chip Carrier 20108055 See NS Package Number E20A Dual-In-Line Package 20108001 Top View See NS Package Number J14A 20108033 See NS Package Number W14B or WG14A www.national.com 2 LM124AQML/LM124QML Schematic Diagram (Each Amplifier) 20108002 3 www.national.com LM124AQML/LM124QML Absolute Maximum Ratings (Note 2) Supply Voltage, V+ Differential Input Voltage Input Voltage Input Current (VIN < -0.3Vdc) (Note 5) Power Dissipation (Note 3) CERDIP CERPACK LCC CERAMIC SOIC Output Short-Circuit to GND (One Amplifier) (Note 4) 32Vdc or 16Vdc 32Vdc -0.3Vdc to +32Vdc 50 mA 1260mW 700mW 1350mW 700mW V+ 15Vdc and TA = 25C Continuous -55C TA +125C 150C Operating Temperature Range Maximum Junction Temperature Storage Temperature Range -65C TA +150C 260C Lead Temperature (Soldering, 10 seconds) Thermal Resistance ThetaJA 103C/W CERDIP (Still Air) (500LF/Min Air flow) 51C/W 176C/W CERPACK (Still Air) (500LF/Min Air flow) 116C/W 91C/W LCC (Still Air) (500LF/Min Air flow) 66C/W 176C/W CERAMIC SOIC (Still Air) (500LF/Min Air flow) ThetaJC CERDIP CERPACK LCC CERAMIC SOIC Package Weight (Typical) CERDIP CERPACK LCC CERAMIC SOIC ESD Tolerance (Note 6) www.national.com 116C/W 19C/W 18C/W 24C/W 18C/W 2200mg 460mg 470mg 410mg 250V 4 LM124AQML/LM124QML Quality Conformance Inspection MIL-STD-883, Method 5005 - Group A Subgroup Description 1 Static tests at Temp ( C) +25 2 Static tests at +125 3 Static tests at -55 4 Dynamic tests at +25 5 Dynamic tests at +125 6 Dynamic tests at -55 7 Functional tests at +25 8A Functional tests at +125 8B Functional tests at -55 9 Switching tests at +25 10 Switching tests at +125 11 Switching tests at -55 5 www.national.com LM124AQML/LM124QML LM124/883 Electrical Characteristics SMD: 77043 DC Parameters (The following conditions apply to all the following parameters, unless otherwise specified.)

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/ ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower. Note 4: 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 +15VDC, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. Note 5: 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 -0.3VDC (at 25C).

Note 8: Datalog reading in K=V/mV Note 9: Guaranteed, not tested Note 10: Calculated parameters Note 11: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics except as listed in the Post Radiation Limits Table. These parts may be dose rate sensitive in a space environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters are guaranteed only for the conditions as specified in MIL-STD-883, Method 1019 Note 12: Low dose rate testing has been performed on a wafer-by-wafer basis, per test method 1019 condition D of MIL-STD-883, with no enhanced low dose rate sensitivity (ELDRS) effect. Note 13: 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 14: 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 independent of the magnitude of V+. Note 15: 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.

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 should be provided to prevent the input voltages from going negative more than -0.3 VDC (at 25C). 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 15 www.national.com LM124AQML/LM124QML 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 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 25C 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, 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.
