PAM8403 3W Stereo Digital Audio Amplifier Board – Compact Red PCB Design

Description

The Mini Digital Power Amplifiers 3W Dual Track Red PAM8403 provides Class AB power amplifier performance with Class D amplifier efficiency. The use of low noise, no filter structure can save the traditional D class amplifier output low pass filter. Requires very few external components, thus saving PCB space and system cost, is ideal for portable applications.

The PAM8403 provides 3W of power at efficiencies greater than 90% with both system shutdown and mute control. Special line architecture enhances anti-noise capability and reduces RF interference.
PAM8403 Features: No filter Class D amplifier, low quiescent current, and low EMI, up to 3W output power at 4 load and 5v power supply conditions. Up to 90 ℅ efficiencies, low THD, low noise, short circuit current protection, thermal protection, very few external components, saving cost and space.
