Frequently Asked Questions
How much output power does the PAM8403DR-H deliver per channel and into which speaker impedances?
The PAM8403DR-H delivers up to 3W per channel into a 4Ω load at 5V supply voltage, with the dual-channel design providing 6W total stereo output, making it suitable for compact speaker systems in portable audio products and smart home devices.
Does the PAM8403DR-H require output LC filters, and how does that affect PCB design complexity?
The PAM8403DR-H uses a filterless Class D architecture that eliminates the need for external LC output filters, reducing PCB component count by up to 6 passive components per channel, lowering BOM cost, and freeing approximately 50–100 mm² of board area in tight speaker amplifier layouts.
What supply voltage range does the PAM8403DR-H accept, and is it compatible with USB 5V powered designs?
The PAM8403DR-H operates from a 2.5V to 5.5V supply voltage range, making it fully compatible with USB 5V rails, single-cell LiPo batteries at 3.7V, and regulated 3.3V logic supplies, covering a wide range of portable and battery-powered audio application designs.
