Overview

The PAM8610 is a 10W per channel, stereo Class-D audio power amplifier designed to drive speakers without the need for bulky external heat sinks or LC filters. It operates across a 7V to 15V supply range and features high efficiency, making it suitable for compact, battery-powered, or space-constrained consumer electronics. The device includes comprehensive protection circuitry and pop-noise suppression to ensure reliable operation and high-quality audio output.

Why Choose This Part

The PAM8610 offers filterless architecture and integrated pop-noise suppression, significantly reducing the external component count and PCB footprint. Its high efficiency and low idle current of 20mA minimize thermal management requirements, allowing for sleek enclosure designs. Integrated safety features including over-current, thermal, and short-circuit protection provide robust performance in various operating environments.

Applications

Flat Panel Displays

Ideal for driving internal stereo speakers in LCD monitors and TVs where board space is limited.

Portable Multimedia Systems

Used in battery-powered boom boxes and portable speaker docks due to its low 4uA shutdown current.

Gaming Machines

Provides high-efficiency audio amplification for arcade or kiosk applications with minimal thermal overhead.

Electronic Musical Instruments

Serves as a compact output stage for digital keyboards and synthesizers.

Getting Started

When designing with the PAM8610, prioritize a low-ESR decoupling capacitor placed as close as possible to the VDD pins to handle high-frequency switching currents. Use a solid ground plane and minimize the length of speaker traces to reduce EMI, as this is a Class-D amplifier. While no LC filter is required for short cable runs, engineers should evaluate the need for ferrite beads if EMI compliance is a concern in the final housing.
