PAM8610TR

Overview

The PAM8610TR is a 10W per channel stereo Class-D audio power amplifier manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 7V to 15V and features integrated DC volume control with 32 steps spanning +32dB to -75dB. The device delivers high efficiency exceeding 90% and maintains low total harmonic distortion plus noise (THD+N) of 0.1%. It includes comprehensive protection mechanisms such as over-current, thermal shutdown, and short-circuit protection. The component is housed in a compact 40-pin QFN 6mm x 6mm package.

Feature Summary

• Integrated 32-step DC volume control for precise gain adjustment
• High energy conversion efficiency exceeding 90%
• Low output noise floor at -90dB
• Built-in pop noise suppression during startup and shutdown

Applications

• Flat monitors and LCD TVs
• Multi-media speaker systems
• DVD players and game machines
• Boom boxes
• Musical instruments

Procurement Notes

Verify the datasheet revision status before procurement, as the document indicates this part is not recommended for new designs. Confirm that the specific TR suffix corresponds to the Tape & Reel shipping format containing 2500 units per reel. Ensure the design accommodates the required thermal land area for the exposed pad to maintain safe operating junction temperatures.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components within a 7V to 15V supply range. The integrated DC volume control simplifies interface requirements compared to analog volume potentiometers. Consider the 40-pin QFN package dimensions when designing the PCB footprint and verify that the thermal resistance characteristics meet the ambient temperature requirements of the final enclosure.

Part Context

The PAM8610 is a stereo Class-D audio amplifier designed for medium-power audio reproduction. It utilizes pulse-width modulation technology to achieve high efficiency while maintaining low distortion. The device integrates an internal oscillator and bootstrap capacitors management, reducing the need for external passive components. It supports both differential and single-ended input configurations through its dedicated audio input pins.

Replacement Considerations

The datasheet explicitly recommends using the PAM8006A as the replacement for new designs.
