Class D Mono Amplifier Module TPA3110 30W 4 Ohm
The Wondom AA-AB31471 is a small, simple and efficient Class D mono amplifier module. It includes a TPA3110 TI chip to enable it to provide a power of 30W for an efficiency of 90%, as well as a precise sound reproduction. In addition, the module has very good heat dissipation, eliminating the need for a heat sink and ensuring long durability. The circuit is also protected by a series of overload, high temperature and reverse polarity protection.
