High Power 100W Mono Digital Power Amplifier Board TDA7294 HIFI Amplifier Module

About this deal

This is a single-channel Class-AB audio amplifier board built around the STMicroelectronics TDA7294 DMOS power amplifier IC. The rated non-distortion output power is 85W, with a peak power of 100W. It requires a dual 12-36V toroidal transformer supply, with a dual 32V toroid recommended, and supports speaker impedances of 4 to 8 ohms. It is well suited to high-power mono applications such as subwoofers or dedicated hi-fi speaker channels. The board is intended for DIY builders who are comfortable working with linear power supplies and proper heatsinking. A heatsink must be fitted, as without one the chip will overheat and risk burnout. A power supply and heatsink are not included, so factor these into your build.
