PAM8610 Digital Stereo Class-D Audio Amplifier Module

Key Features:

1. Digital Class-D Amplification: Utilizes Class-D amplifier technology for high efficiency and low heat dissipation, making it ideal for battery-powered applications.
2. Output Power: Can deliver up to 10 watts per channel (at 10% THD, with a 4-ohm load), or around 6 watts per channel with an 8-ohm load. This is suitable for driving small to medium-sized speakers in DIY audio projects.
3. Wide Voltage Range: Operates on a wide supply voltage range, typically from 7V to 15V DC, making it versatile for various power supply options.
4. Compact Size: Small form factor allows for easy integration into compact designs such as mini boom boxes, portable speakers, and other audio projects.
5. Low Quiescent Current: Consumes minimal current when idle, contributing to longer battery life in portable applications.
6. Low THD (Total Harmonic Distortion): Provides clean audio output with low distortion, ensuring high-fidelity sound reproduction.
7. Built-in Protection Circuitry: Includes overcurrent protection and thermal shutdown protection to prevent damage to the amplifier module and connected speakers.
