Additional Details:
The PAM8006HR operates from a single power supply, typically in the range of 2.5V to 5.5V. The filter-less Class-D architecture eliminates the need for external LC filters, reducing BOM cost and board space. The amplifier incorporates comprehensive protection features, including short-circuit protection, thermal shutdown protection, and over-current protection, ensuring reliable operation even under fault conditions. The UVLO feature prevents the amplifier from operating when the supply voltage is too low, preventing damage to the speakers.
The PAM8006HR's high efficiency minimizes power dissipation, making it an excellent choice for battery-powered devices. Its low THD+N ensures clear and accurate audio reproduction. The device is available in a small SOP-16 (Small Outline Package) making it easy to integrate into compact designs.
