Mikroelektronika MIKROE-3077 TDA7491 Audio Amp 2 Click Dual BTL Class D Amplifier

Technical description of the product (MIKROE-3077):

MIKROE-3077 TDA7491. 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 the 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. Type: Audio. Key Features: High output power with low dissipation, requiring no heat sinks, low THD and SNR, integrated short circuit detection, undervoltage, and overtemperature protection. Interface: GPIO. Input Voltage: 3.3V, 5V. Click Board size: L (57.15 x 25.4 mm).
