PAM8403ADR

Overview

The PAM8403ADR is a filterless Class-D stereo audio amplifier manufactured by Diodes Incorporated. It delivers 3W of output power into a 4-ohm load with a total harmonic distortion plus noise (THD+N) of 0.15%. The device operates on a supply voltage ranging from 2.5V to 5.5V and draws a typical operating current of 16mA. It is housed in a 16-SOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Filterless architecture eliminates the need for external output filters, reducing component count and board space.
• Integrated protection mechanisms include depop, short-circuit, and thermal shutdown capabilities.
• Low THD+N performance ensures high-quality sound reproduction for audio applications.

Applications

• Portable media players
• Mobile phones
• Personal digital assistants
