DIOPAM8403DR-H
Overview
The PAM8403DR-H is a 3W, stereo, filterless Class-D audio amplifier designed for high-efficiency audio reproduction in space-constrained applications. It operates from a 2.5V to 5.5V supply and provides a low-component-count solution by eliminating the need for bulky LC output filters. This amplifier achieves up to 90 percent efficiency and includes integrated short-circuit protection and thermal shutdown.
Why Choose This Part
The filterless architecture reduces overall system cost and board space by removing the output LC filter. It features low THD+N and superior low noise performance, combined with a 20uA shutdown current for power-sensitive designs.

Key Specifications
Getting Started
To evaluate this IC, look for PAM8403 breakout boards which provide 2.54mm headers for input, power, and speaker outputs. Ensure adequate decoupling capacitors are placed near the VDD pin and follow datasheet layout guidelines regarding thermal pads to manage heat at 3W power levels.
