Diodes Incorporated - New stereo Class-D audio power amplifier targets wireless media speakers

Diodes Incorporated PAM8106 features low THD + N, low EMI, and high PSRR. It is a 10W stereo Class D audio amplifier with integrated SSM and NCPL technology. It can be used for a variety of battery or line power equipment including wireless speakers, LCD Offers premium feature TVs, portable stereos and game consoles. The device operates over a wide input voltage range (4.5V to 15V) and is capable of driving 8Ω and 4Ω speakers. Its high efficiency of up to 92% reduces heat generation and eliminates the need for a heat sink, thus avoiding the cost, weight and space of adding a heat sink in the final application. With a quiescent current of only 15mA, the device is ideally suited for Li + or alkaline battery-powered portable speakers, providing longer audio enjoyment and better sound quality. The device also features NCPL technology, which automatically adjusts the gain to eliminate clipping of the output signal due to high-level input signals. The device also has a low THD + N for further speaker protection. Additional protection integrated into the device prevents short circuit failures, and also integrates thermal shutdown, undervoltage and DC input protection.
