Super mini Digital Amplifier Board details

Super-mini digital amplifier board adopts ultra-thin board and can be put into small cases or interstices of other devices. For example it can be made as external small speaker for MP3/4 or laptop. As for this Super-mini digital amplifier board, 5V input can generate [3 x 2]6W power. We recommend that you adopt USB(5V) or single lithium cell as power supply.

Strengths:

Special internal output processing circuit;

The cancellation of traditional LC network leads to much lower EMI value!

Able to achieve maximum power output under lower voltage, super power-saving!

Built-in standby switch, high-gain buffer amplifier and short-circuit protection.

Power supply:

3.6～5.5V

Power-up by single lithium cell, USB(5V) or four 1.2V batteries.

Note:

Power supply by transformer must be accompanied by 5V voltage stabilizing circuit because over 5.5V may lead to the burn-out of the chip.
