Audio Amp 2 click 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 8Ω 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.

AudioAmp 5 Click is a stereo audio amplifier, capable of delivering up to 10W per channel with the 8Ω load. It is based on the TPA3138D2, a class-D integrated amplifier, which utilizes a highly efficient switching scheme. With about 20mA in idle mode, it allows for longer operation and improved thermal performance, making it a perfect choice for various battery-powered applications. Advanced EMI Suppression with Spread Spectrum Control allows using ferrite bead filters instead of bulky inductors, still maintaining the required EMC levels. The TPA3138D2 IC is equipped with a set of protection features, allowing a reliable operation.

AudioAmp 5 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
