## Description

PAM8406 digital amplifier board 5W×2 volume adjustable D class module : desertcart.in: Electronics

Review: Good product - Product is very good and both the boards are working well. I couldn't test the boards before so now I tested them on 8 ohms speakers and 5 Volt regulated suppy and although the sound output is low (0.5 watts per channel approx) the sound quality is good. The Ic gets warm after sometime because it's configured in class AB mode instead of D mode which has to changed to class D mode for less heat dissipation by connecting pin 9 of the Ic to positive of power supply instead of ground according to datasheet of this Ic pam 8406. Highly recommended for Diy enthusiasts who want to make a Diy sound system for computers or cellphones
Review: Good - Good. Little heating but ok

*by T***O on 27 November 2025*

Good. Little heating but ok

### ⭐⭐⭐ encounter similar heating issues.
*by M***. on 14 March 2023*

The PAM8406 amplifier IC can generate a significant amount of heat when operating at higher power levels, and this heat can cause the amplifier board to malfunction or even fail. Therefore, adding a heatsink to the PAM8406 amplifier board can help dissipate the heat generated by the IC and improve the overall thermal performance of the amplifier. suggest to the seller that they offer the option to purchase the board with a heatsink included in the future, as this may be helpful for other customers who may also encounter similar heating issues.
