It is intended for a wide range of analog applications. The high gain and wide range of operating voltage provide superior performance in integrator, summing amplifier, and general feedback applications. The LM741-MIL operates with either a single or dual power supply voltage. The LM741MIL device is a direct, plug-in replacement for the 709C, LM201, MC1439, and 748 in most applications. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 Overload Protection The LM741-MIL features overload protection circuitry on the input and output. This prevents possible circuit damage to the device. 7.3.2 Latch-up Prevention The LM741-MIL is designed so that there is no latch-up occurrence when the common-mode range is exceeded. This allows the device to function properly without having to power cycle the device. 7.3.3 Pin-to-Pin Capability The LM741-MIL is a pin-to-pin direct replacement for the LM709C, LM201, MC1439, and LM748 in most applications. Direct replacement capabilities allows flexibility in design for replacing obsolete parts. 6 Submit Documentation Feedback Copyright (c) 2017, Texas Instruments Incorporated Product Folder Links: LM741-MIL LM741-MIL www.ti.com SNOSD62 - JUNE 2017 7.4 Device Functional Modes 7.4.1 Open-Loop Amplifier The LM741-MIL can be operated in an open-loop configuration. The magnitude of the open-loop gain is typically large thus for a small difference between the non-inverting input terminals and the inverting input terminals, the amplifier output is driven near the supply voltage. Without negative feedback, the LM741-MIL can act as a comparator. If the inverting input is held at 0 V, and the input voltage applied to the non-inverting input is positive, the output will be positive. If the input voltage applied to the non-inverting input is negative, the output is negative. 7.4.2 Closed-Loop Amplifier In a closed-loop configuration, negative feedback is used by applying a portion of the output voltage to the inverting input. Unlike the open-loop configuration, closed loop feedback reduces the gain of the circuit. The overall gain and response of the circuit is determined by the feedback network rather than the operational amplifier characteristics. The response of the operational amplifier circuit is characterized by the transfer function.

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 LM741-MIL is a general-purpose amplifier than can be used in a variety of applications and configurations. One common configuration is in a non-inverting amplifier configuration. In this configuration, the output signal is in phase with the input (not inverted as in the inverting amplifier configuration), the input impedance of the amplifier is high, and the output impedance is low. The characteristics of the input and output impedance is beneficial for applications that require isolation between the input and output. No significant loading will occur from the previous stage before the amplifier. The gain of the system is set accordingly so the output signal is a factor larger than the input signal. 8.2 Typical Application R2 4.7 NY +VSUPPLY LM741-MIL R1 4.7 NY VINPUT VSUPPLY 1 OFFSET_NULL NC 8 2 INVERTING_INPUT V+ 7 3 NON-INVERTING_INPUT 4 V OUTPUT 6 OFFSET_NULL 5 VOUT Copyright (c) 2017, Texas Instruments Incorporated Figure 1. LM741-MIL Noninverting Amplifier Circuit 8.2.1 Design Requirements As shown in Figure 1, the signal is applied to the noninverting input of the LM741-MIL. The gain of the system is determined by the feedback resistor and input resistor connected to the inverting input. The gain can be calculated by Equation 1: Gain = 1 + (R2/R1) (1) The gain is set to 2 for this application. R1 and R2 are 4.7-k resistors with 5% tolerance. 8.2.2 Detailed Design Procedure The LM741-MIL can be operated in either single supply or dual supply. This application is configured for dual supply with the supply rails at 15 V. The input signal is connected to a function generator. A 1-VPP, 10-kHz sine wave was used as the signal input. 5% tolerance resistors were used, but if the application requires an accurate gain response, use 1% tolerance resistors. 8.2.3 Application Curve The waveforms in Figure 2 show the input and output signals of the LM741-MIL non-inverting amplifier circuit. The blue waveform (top) shows the input signal, while the red waveform (bottom) shows the output signal. The input signal is 1.06 VP-P and the output signal is 1.94 VP-P. With the 4.7-k resistors, the theoretical gain of the system is 2. Due to the 5% tolerance, the gain of the system including the tolerance is 1.992. The gain of the system when measured from the mean amplitude values on the oscilloscope was 1.83. 8 Submit Documentation Feedback Copyright (c) 2017, Texas Instruments Incorporated Product Folder Links: LM741-MIL LM741-MIL www.ti.com SNOSD62 - JUNE 2017 Typical Application (continued) Figure 2. Waveforms for LM741-MIL Non-inverting Amplifier Circuit 9 Power Supply Recommendations For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines, a 0.1-F capacitor is recommended and should be placed as close as possible to the LM741-MIL power supply pins. 10 Layout 10.1 Layout Guidelines As with most amplifiers, take care with lead dress, component placement, and supply decoupling in order to ensure stability. For example, resistors from the output to an input should be placed with the body close to the input to minimize pick-up and maximize the frequency of the feedback pole by minimizing the capacitance from the input to ground. As shown in Figure 3, the feedback resistors and the decoupling capacitors are located close to the device to ensure maximum stability and noise performance of the system. 10.2 Layout Example Figure 3.
