Mini Digital Power Amplifiers 3W Dual Track Red PAM8403

Class AB power amplifier performance combined with Class D amplifier efficiency is offered by the Mini Digital Power Amplifiers 3W Dual Track Red PAM8403. The conventional D class amplifier output low pass filter cannot be saved by the use of low noise and no filter structure. is perfect for portable applications since it requires extremely few external components, minimising PCB space and system costs.

The PAM8403 offers mute control and system shutdown together with 3W of power at efficiencies of over 90%. Reduced RF interference and improved anti-noise capability are achieved by special line architecture.
PAM8403 Characteristics: Low quiescent current, low EMI, no filter Class D amplifier with up to 3W of output power under 4 load and 5 volt power supply conditions. Features include low THD, low noise, short circuit current protection, thermal protection, up to 90 °C efficiency, relatively few external components, and space and cost savings.

Features :

1. A d-type amplifier without a filter, low quiescent current, and low EMI.
2. When connects with a 4-ohm load and 5V power supply, the output power can be up to 3W.
3. Low THD, low noise.
4. Short circuit protection; thermal protection.
