Mini Digital Power Amplifiers 3W Dual Track Red PAM8403
The Mini Digital Power Amplifiers 3W Dual Track Red PAM8403 combines the performance of Class AB power amplifiers with the efficiency of Class D power amplifiers. It does not need a low-pass filter at the output, unlike traditional Class D amplifiers, which reduces noise and saves space. It is ideal for portable applications because it requires very few external components.
The PAM8403 can deliver 3W of power with more than 90% efficiency and has both system shutdown and mute control features. It also has a special line architecture that improves noise immunity and reduces RF interference.
PAM8403 Features: Filterless Class D amplifier with low quiescent current and low EMI. Up to 3W output power at 4 ohm load and 5v power supply. High efficiency up to 90%, low THD, low noise. Short circuit current protection, thermal protection. Minimal external components, saving cost and space.
