LM380 vs LM386: What are Differences and How to Choose

The LM380 and LM386 are two popular audio amplifier integrated circuits that have earned their place in the world of electronics due to their compact size and audio amplification capabilities. While both ICs are designed to amplify audio signals, they differ in terms of features, performance, and applications.

Part 1. What are Audio Amplifier Integrated Circuits

Audio amplifier integrated circuits (ICs) are electronic devices designed to amplify low-power audio signals from sources like microphones, musical instruments, or audio players. These ICs provide the necessary gain and power to drive speakers, headphones, or other audio output devices. They are commonly used in a wide range of applications to enhance the volume and quality of audio signals.

Audio amplifier ICs come in various configurations and power levels to accommodate different audio system requirements. They can be used in devices such as audio receivers, portable speakers, headphones, intercom systems, radios, musical instruments, and more. These ICs simplify circuit design by integrating amplifier circuitry into a single package, reducing the need for external components and simplifying the overall design process.

Part 2. What is LM380

The LM380 is a type of integrated circuit (IC) or chip that functions as an audio amplifier. It is designed to amplify low-power audio signals to a level suitable for driving speakers or headphones. The LM380 is commonly used in various audio applications, such as portable radios, intercom systems, small public address (PA) systems, and other electronics where audio amplification is needed.

Part 3. What is LM386

The LM386 is a widely used audio amplifier integrated circuit (IC) that is designed to amplify low-power audio signals. It's a popular choice for various audio applications due to its simplicity, ease of use, and relatively low component count. The LM386 is commonly used in projects where amplifying audio signals from sources like microphones, radios, or other audio devices is necessary.
