3W + 3W Stereo Audio Class-D Amplifier PAM8403 with Volume Control

Description

The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction.

The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.

With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins.

It can extend the battery life, which makes it well-suited for portable applications.

Features:
– 3W Output at 10% THD with a 4Ω Load and 5V Power Supply
– Filterless, Low Quiescent Current and Low EMI
– Low THD+N
– Superior Low Noise
– Efficiency up to 90%
– Short Circuit Protection
– Thermal Shutdown
– Volume knob on board
