If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. 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 -0.3 V (at 25C). For operating at high temperatures, the LM324-N/LM324A/LM2902-N must be derated based on a 125C maximum junction temperature and a thermal resistance of 88C/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 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. 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 15 V, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. 6.2 ESD Ratings V(ESD) (1) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) VALUE UNIT 250 V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN MAX Supply Voltage (V+ - V-): LM124-N/LM124A/LM224-N/LM224A/LM324-N/LM324A 3 32 V Supply Voltage (V+ - V-): LM2902-N 3 26 V Operating Input Voltage on Input pins UNIT 0 V+ V Operating junction temperature, TJ: LM124-N/LM124A -55 125 C Operating junction temperature, TJ: L2902-N -40 85 C Operating junction temperature, TJ: LM224-N/LM224A -25 85 C Operating junction temperature, TJ: LM324-N/LM324A 0 70 C 4 Submit Documentation Feedback Copyright (c) 2000-2015, Texas Instruments Incorporated Product Folder Links: LM124-N LM224-N LM2902-N LM324-N LM124-N, LM224-N LM2902-N, LM324-N www.ti.com SNOSC16D - MARCH 2000 - REVISED JANUARY 2015 6.4 Thermal Information THERMAL METRIC RJA (1) (1) LM124-N / LM224-N LM324-N / LM2902-N J/CDIP D/SOIC 14 PINS 14 PINS 88 88 Junction-to-ambient thermal resistance UNIT C/W For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 6.5 Electrical Characteristics: LM124A/224A/324A V+ = 5.0 V, (1) , unless otherwise stated PARAMETER TEST CONDITIONS LM124A MIN LM224A TYP MAX MIN LM324A TYP MAX MIN TYP MAX UNIT Input Offset Voltage TA = 25C (2) 1 2 1 3 2 3 mV Input Bias Current (3) IIN(+) or IIN(-), VCM = 0 V, TA = 25C 20 50 40 80 45 100 nA Input Offset Current IIN(+) or IIN(-), VCM = 0 V, TA = 25C 2 10 2 15 5 30 nA Input Common-Mode Voltage Range (4) V+ = 30 V, (LM2902-N, V+ = 26 V), TA = 25C V+-1.5 V Supply Current Over Full Temperature Range, RL = On All Op Amps V+ = 30 V (LM2902-N V+ = 26 V) V+-1.5 0 1.5 V+-1.5 0 3 1.5 0 3 1.5 3 mA + 0.7 V =5V 1.2 0.7 1.2 0.7 1.2 Large Signal Voltage Gain V+ = 15 V, RL 2 k, (VO = 1 V to 11 V), TA = 25C 50 100 50 100 25 100 V/mV Common-Mode Rejection Ratio DC, VCM = 0 V to V+ - 1.5 V, TA = 25C 70 85 70 85 65 85 dB Power Supply Rejection Ratio V+ = 5 V to 30 V, (LM2902-N, V+ = 5V to 26 V), TA = 25C 65 100 65 100 65 100 dB Amplifier-to-Amplifier Coupling (5) f = 1 kHz to 20 kHz, TA = 25C, (Input Referred) -120 dB mA Source Output Current Sink 20 40 20 40 20 40 VIN- = 1 V, VIN+ = 0 V, V+ = 15 V, VO = 2 V, TA = 25C 10 20 10 20 10 20 VIN- = 1 V, VIN+ = 0 V, V+ = 15 V, VO = 200 mV, TA = 25C 12 50 12 50 12 50 V+ = 15 V, TA = 25C (6) Input Offset Voltage See (2) VOS Drift RS = 0 Input Offset Current IIN(+) - IIN(-), VCM = 0 V (2) (3) (4) (5) (6) -120 VIN+ = 1 V, VIN- = 0 V, V+ = 15 V, VO = 2 V, TA = 25C Short Circuit to Ground (1) -120 A 40 60 7 20 40 60 7 20 4 40 60 5 mV 7 30 V/C 75 nA 4 30 30 mA These specifications are limited to -55C TA +125C for the LM124-N/LM124A.

This current is essentially constant, independent of the state of the output so no loading change exists on the input lines.

This typically can be detected as this type of capacitance increases at higher frequencies. Short circuits from the output to V+ can cause excessive heating and eventual destruction.

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. 7.2 Functional Block Diagram 7.3 Feature Description The LM124 provides a compelling balance of performance versus current consumption. The 700 A of supply current draw over the wide operating conditions with a 1-MHz gain-bandwidth and temperature compensated bias currents makes the LM124 an effective solution for large variety of applications. The input offset voltage of 2 mV and offset current of 5 nA, along with the 45n-A bias current across a wide supply voltage means a single design can be used in a large number of different implementations. 7.4 Device Functional Modes 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 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.

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 Characteristics) than a standard IC op amp. 12 Submit Documentation Feedback Copyright (c) 2000-2015, Texas Instruments Incorporated Product Folder Links: LM124-N LM224-N LM2902-N LM324-N LM124-N, LM224-N LM2902-N, LM324-N www.ti.com 8 SNOSC16D - MARCH 2000 - REVISED JANUARY 2015 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LM124 series of amplifiers is specified for operation from 3 V to 32 V (1.5 V to 16 V). Many of the specifications apply from -40C to 125C. Parameters that can exhibit significant variance with regards to operating voltage or temperature are presented in Typical Characteristics. 8.2 Typical Applications Figure 15 emphasizes 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. 8.2.1 Non-Inverting DC Gain (0 V Input = 0 V Output) *R not needed due to temperature independent IIN Figure 15. Non-Inverting Amplifier with G=100 8.2.1.1 Design Requirements For this example application, the required signal gain is a non-inverting 100x5% with a supply voltage of 5 V. 8.2.1.2 Detailed Design Procedure Using the equation for a non-inverting gain configuration, Av = 1+R2/R1. Setting the R1 to 10 k, R2 is 99 times larger than R1, which is 990 k. A 1M is more readily available, and provides a gain of 101, which is within the desired specification. The gain-frequency characteristic of the amplifier and its feedback network must be such that oscillation does not occur. To meet this condition, the phase shift through amplifier and feedback network must never exceed 180 for any frequency where the gain of the amplifier and its feedback network is greater than unity. In practical applications, the phase shift should not approach 180 since this is the situation of conditional stability. Obviously the most critical case occurs when the attenuation of the feedback network is zero.

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. 10 Layout 10.1 Layout Guidelines The V + pin should be bypassed to ground with a low-ESR capacitor. The optimum placement is closest to the V + and ground pins. Take care to minimize the loop area formed by the bypass capacitor connection between V + and ground. The ground pin should be connected to the PCB ground plane at the pin of the device. The feedback components should be placed as close to the device as possible minimizing strays. 10.2 Layout Example GND 2 VOUTD 2 VOUTA VOUTA 1 VINA 1 IN-A 2 IN+A GND 1 IN-A IN-A IN+A 1 GND 2 V+ V+ 1: VOUTA VIND VINC 2 GND GND GND GND 2 GND 14: VOUTD VOUTD 2: IN-A 13: IN-D 3: IN+A 12: IN+D 4: V+ 11: GND 1 IN-D IN-D 1 IN-D 1 VIND 2 IN+D IN+D GND NC VI IN-B 1 IN-B 1 IN-B 2 GND 2 VOUTB IN+C 6: IN-B 9: IN-C IN-C 7: VOUTB 2 IN+C 1 VINC 1 IN-C 1 IN-C 2 VOUTC 2 GND VINC 8: VOUTC VOUTC GND VOUTB 10: IN+C VOUTD 1 VINB 5: IN+B VOUTA IN+B 2 IN+B GND GND Figure 43.
