Product Overview: Texas Instruments LM386N-4 Audio Power Amplifier

The LM386N-4 from Texas Instruments is a versatile and compact audio power amplifier integrated circuit designed for consumer electronics applications. This low voltage audio power amplifier is housed in an 8-pin plastic DIP (Dual In-line Package), making it ideal for prototyping and small-scale production.

The LM386N-4 is a higher-gain version of the LM386 audio amplifier series, capable of delivering 1 watt of continuous average power to an 8-ohm load with 0.5% total harmonic distortion (THD) from a 5V power supply. This makes it an excellent choice for battery-powered devices such as portable speakers, radios, and musical instruments.

A key feature of the LM386N-4 is its minimal external part requirement, which simplifies the design and reduces the overall bill of materials for product development. The amplifier is internally compensated and does not require external frequency compensation components. It also includes features like a bypass pin for superior low noise performance and an external gain setting function.

The LM386N-4 operates over a wide power supply range of 4V to 12V, providing flexibility in various application scenarios. Additionally, it is equipped with several self-protection features, including short-circuit protection and thermal shutdown, ensuring reliability and longevity of the end product.

Texas Instruments' LM386N-4 is a tried-and-true solution for a broad range of audio amplification needs. Its ease of use, combined with the reputation of Texas Instruments for producing high-quality, reliable components, makes it a go-to choice for designers and hobbyists alike looking to add audio functionality to their projects without the complexity of designing an amplifier circuit from scratch.
