The 2x30W Amp Click Board™ is a class-D audio amplifier with 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 short circuit detection, with the error reporting feature, via the dedicated pin.
