Welcome to use this 2 x 150W Class-D audio amplifier board by Sure Electronics.

It integrates NXP’s high performance TDA8950 supporting dual channel audio amplification.

Both of channels are capable of outputting nominal power simultaneously and continuously with appropriate symmetrical power supply.

It has built-in linear FAN controller based on the temperature rise to keep noise from the FAN as low as possible while ensure the prompt heat dissipation.

High reliability is ensured due to extensive protection, including overtemperature turn-off, over current protection, over voltage protection.

It’s suitable for amplifier enthusiasts or hobbyists to finish a complete amplifier system.
