PAM8004DR_02

Overview

The PAM8004 is a filterless Class-D stereo audio amplifier manufactured by Diodes Incorporated. It delivers 3W output at 10% THD with a 3Ω load and 5V supply, or 2.5W into a 4Ω load. The device operates on a single power supply ranging from 2.5V to 5.5V and functions within an ambient temperature range of -40°C to +85°C. Packaged in SOP-16L, it features low quiescent current, low EMI, short circuit protection, and thermal shutdown.

Feature Summary

• Filterless architecture eliminates the need for external low-pass output filters, reducing system cost and PCB area.
• High efficiency compared to Class-AB amplifiers, extending battery life in portable applications.
• Integrated protection mechanisms including short circuit protection, thermal shutdown, and under-voltage lock-out.

Applications

• Portable speakers
• LCD monitors and televisions
• Notebook computers
• Portable DVD players and game machines
