PAM8406 Digital Amplifier Board 5W×2 Volume Adjustable D class module

PAM8406 Digital Amplifier Module designed with Volume Control Potentiometer features Excellent noise suppression. The PAM8406 based on an integrated 5W audio amplifier with an alternative option between Class-D and Class-AB output. This makes PAM8406 ideal for applications such as efficiency-EMI compatible. PAM8406 features low THD+N, high SNR providing high-quality sound reproduction. It offers a fully differential output with class D mode (Class-D Mode) allows the device to drive the speaker directly, requiring no low-pass output filters and DC blocking capacitors. Thus saves the system cost and minimum PCB area. PAM8406 offers an efficiency of up to 90%. Moreover,  PAM8406 fully protected with short circuit protection and thermal protection.

As this PAM8406 Digital Amplifier Module provides Volume Control Potentiometer features Excellent noise suppression. Thus you can hear any noise without connecting input audio. This module with a Dual-channel stereo, requires a 5v power supply that can input 5w+5w power, to drive 4, 8 little speaker directly. Thereby provides large output power, enough energy, superior quality, and left-right channel volume adjustment. The unique non-LC filter class-D digital power board supports computer USB to charge. This supermini design, with Dual-panel wiring, solves the ground potential balance and avoids the crosstalk between channels caused by wiring. It operates at a voltage range from 2.5v to 5v and the limited operating voltage is 5. 5v.

Note: While connecting the “negative” of the left and right channel output port, It should not be connected together. otherwise, it will damage IC. And the speaker should be charged before connecting charging.
