PAM8320RDR

Overview

The PAM8320RDR is a mono Class-D audio power amplifier manufactured by Diodes Incorporated. It delivers 20W of output power into a 4Ω bridge-tied-load (BTL) speaker when supplied with 12V. The device operates within a supply voltage range of 4.5V to 15V and achieves high efficiency up to 95%, eliminating the need for external heat sinks during music playback. It features an internal oscillator, single-ended analog input, and integrated protection mechanisms including thermal shutdown, short-circuit protection, over-voltage protection, and under-voltage lock-out.

Feature Summary

• High-efficiency Class-D operation eliminates the requirement for external heat sinks
• Integrated thermal and short-circuit protection with automatic recovery
• Anti-pop circuitry minimizes turn-on and turn-off transients
• Internal oscillator removes the need for external timing components

Applications

• PC Speakers
• Bluetooth Speakers
• Home Sound Systems
• Active Speakers
• Docking Stations

Procurement Notes

Verify that the component matches the SO-16EP package configuration and the RDR tape-and-reel shipping format. Confirm the manufacturer is Diodes Incorporated and check datasheet revision DS36610 Rev. 1-2 for accurate electrical specifications. Ensure the application environment supports the specified operating temperature range of -40°C to +85°C.

Selection Notes

Select this amplifier for applications requiring high output power in a compact form factor without active cooling. It is suitable for systems powered between 4.5V and 15V driving 4Ω loads. Consider the PCB thermal design requirements to maximize heat dissipation through copper planes and vias, as recommended for optimal performance at full power.

Part Context

The PAM8320RDR belongs to the PAM8320 series of audio amplifiers from Diodes Incorporated. This series focuses on efficient Class-D technology designed to drive low-impedance speakers directly. The RDR suffix indicates the specific surface-mount packaging and reel quantity configuration used for automated assembly processes.
