TPA3110 30W Dual Channel Digital Power Amplifier Module

TPA3110 30W Dual Channel Digital Power Amplifier ModuleThis high-efficiency TPA3110 30W Dual Channel Digital Power Amplifier Module is engineered to deliver crisp stereo audio performance with minimal thermal dissipation. Furthermore, it utilizes the advanced TPA3110D2 Class D amplifier IC, consequently providing high power output without requiring a bulky heatsink. Therefore, it is an ideal choice for custom DIY Bluetooth speakers, portable audio docks, and desktop sound systems. However, users must ensure the power supply voltage remains within the recommended 8V to 26V range to prevent damaging the internal circuitry. Specifically, the board features onboard filter inductors and large electrolytic capacitors to suppress electrical noise and ensure clean sound reproduction. Moreover, the integrated mute control and short-circuit protection safeguards ensure long-term operational reliability. Ultimately, this amplifier board offers an exceptional balance of high efficiency, compact size, and robust audio output.
