2 x 30W Amp Click Board

The 2x30W Amp Click Board™ is a class-D audio amplifier with a tremendous output power, considering its size and lack of huge heatsinks, usually associated with the audio amplifiers. This is due to the fact that the efficiency of the amplifier IC is quite high (greater than 90%), featuring the efficiency boost mode, which dynamically reduces the current ripple of the external LC filter and current in idle mode. The integrated self-protection circuits include over-voltage, under-voltage, and over-temperature protection, output DC offset detection, as well as the short circuit detection, with the error reporting feature, via the dedicated pin.

2 x 5W Amp Click Board

The 2 x 5W Audio Amplifier Click Board™ functions as an amplifier and features the TDA7491LP 2x5-watt dual BTL class-D audio amplifier. The Click Board™ is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over the following pins on the MikroBUSline: AN, RST, CS, PWM, INT.

The 2 x 5W AMP Click Board™ features a 3.5mm input jack and four output screw terminals for connecting passive speakers.
Note: In order to achieve full 2x5W output power, keep in mind that you need to supply enough current to the chip. This is achievable with the EXT PWR header, but you need to switch over the AMP VCC to the left position.
