AudioAMP 2 Click Board

The Audio Amp 2 Click Board™ is a highly efficient class D audio amplifier, using the TDA7491, a dual BTL class-D audio amplifier IC, capable of delivering up to 20W to 8? load. This amplifier IC features high-efficiency output stage drivers and clever design, allowing it to deliver a reasonably high power to the connected speakers, using only GND polygon on the PCB for heat dissipation. In the BTL topology, the output DC blocking capacitors are not required. This allows for simpler design and lower power losses, especially with no input signal. The TDA7491 amplifier IC is equipped with a set of protection features, that allow reliable operation.
