Description

The LM380 is a monolithic power amplifier designed for general-purpose audio amplification. It operates with a single power supply and provides an output of up to 2.5 watts into an 8Ω load with low distortion. The IC is packaged in a 14-pin Dual In-line Package (DIP-14), making it easy to use on standard circuit boards.

The LM380 includes built-in protection features and is designed to minimize the need for external components, allowing for compact and straightforward circuit designs.

Features

  • Output Power: Provides 2.5W of audio output power into an 8Ω speaker load.
  • Low Distortion: Offers high-quality audio with low harmonic and crossover distortion.
  • Wide Supply Voltage Range: Operates from 10V to 22V, allowing flexibility in different power supply conditions.
  • Internal Gain: Fixed gain of 34 dB, simplifying design and ensuring consistent performance.
  • Built-in Protection: Features thermal shutdown and short-circuit protection to enhance reliability.
  • Minimal External Components: Requires only a few external components for operation, making it easy to design circuits.
  • Low Quiescent Current: Efficient operation with minimal power consumption when idle.
  • Compact Package: Available in a DIP-14 package, which is easy to handle and solder onto standard PCBs.
