MIKROE-3077

Audio Amp 2 Click board™ highly efficient class D audio amplifier using the TDA7491 a dual BTL class-D audio amplifier IC capable of delivering up to 20W to 8ohm 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.

• 3.3V, 5V input voltage
• GPIO interface
• High output power with low dissipation
• Integrated short circuit detection, undervoltage and overtemperature protection
