Description

The CD4440 / LA4440 is a 2-channel (stereo) audio amplifier IC capable of delivering up to 6W per channel into an 8Ω load. It is built using a silicon monolithic integrated circuit, which ensures consistent performance and high reliability. The IC features built-in protection circuits, making it robust and suitable for a wide range of audio applications.

The device is typically housed in a 14-pin Single In-line Package (SIP14H), which allows for easy integration into audio circuit boards.

Features

  • Dual Channel Output: Provides stereo sound with two independent channels, each capable of delivering 6W into an 8Ω load.
  • High Output Power: Delivers 6W per channel with a wide power supply voltage range.
  • Low Distortion: Ensures clear sound quality with minimal harmonic distortion.
  • Built-in Protection: Includes thermal shutdown, over-voltage, and short-circuit protection circuits to safeguard the IC and connected speakers.
  • Wide Operating Voltage: Operates over a broad range of supply voltages, making it versatile for different power sources.
  • Simple Circuit Design: Requires few external components, reducing design complexity and cost.
  • Heat Dissipation: Designed with efficient heat dissipation to prevent overheating during operation.
