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 can operate with a single or dual power supply voltage. The LM741 devices are direct, plug-in replacements 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 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 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 is pin-to-pin direct replacements for the LM709C, LM201, MC1439, and LM748 in most applications. Direct replacement capabilities allows flexibility in design for replacing obsolete parts.

The magnitude of the open-loop gain is typically large thus for a small difference between the noninverting and inverting input terminals, the amplifier output will be driven near the supply voltage. Without negative feedback, the LM741 can act as a comparator. If the inverting input is held at 0 V, and the input voltage applied to the noninverting input is positive, the output will be positive. If the input voltage applied to the noninverting input is negative, the output will be 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. 8 Submit Documentation Feedback Copyright (c) 1998-2015, Texas Instruments Incorporated Product Folder Links: LM741 LM741 www.ti.com SNOSC25D - MAY 1998 - REVISED OCTOBER 2015 8 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 LM741 is a general-purpose amplifier than can be used in a variety of applications and configurations. One common configuration is in a noninverting 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 = 4.7k +Vsupply R1 = 4.7k - V+ LM741 Vinput + Output V- -Vsupply Figure 1. LM741 Noninverting Amplifier Circuit 8.2.1 Design Requirements As shown in Figure 1, the signal is applied to the noninverting input of the LM741. 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 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.

The blue waveform (top) shows the input signal, while the red waveform (bottom) shows the output signal. The input signal is 1.06 Vpp and the output signal is 1.94 Vpp. 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. Figure 2. Waveforms for LM741 Noninverting 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 power supply pins. 10 Submit Documentation Feedback Copyright (c) 1998-2015, Texas Instruments Incorporated Product Folder Links: LM741 LM741 www.ti.com SNOSC25D - MAY 1998 - REVISED OCTOBER 2015 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.
