Datasheet
Datasheet Summary
Powered by GS/AI

The PAM8403DR is a 3W class-D audio amplifier designed for high-quality sound reproduction with low total harmonic distortion plus noise (THD+N). It features a filterless architecture, allowing direct connection to speakers without the need for low-pass output filters, which reduces system costs and saves PCB space. The amplifier operates efficiently, achieving up to 90% efficiency, making it suitable for battery-powered applications where extended battery life is essential. This device is housed in a SOP-16 package and supports a supply voltage range of 2.5 to 5.5V. It includes protective features such as short circuit protection and thermal shutdown. Typical applications include LCD monitors, notebook computers, portable speakers, and cellular phones. The PAM8403DR is not recommended for new designs, with the PAM8406 suggested as an alternative.
