7 Detailed Description
7.1 Overview
The LM741-MIL device is a general-purpose operational amplifier which features improved performance over
industry standards such as the LM709. 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.

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.

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-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.

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-kΩ 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-kΩ 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.

Typical Application (continued)

9 Power Supply Recommendations
For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines, a 0.1-µF
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.
