PAM8014: 3.2W Mono Class-D Audio Amplifier

The PAM8014 is a 3.2W mono filterless Class-D amplifier with high PSRR and differential input that eliminates noise and RF rectification. It features greater than 90% efficiency and a small PCB area, which makes the PAM8014 Class-D amplifier ideal for portable applications. The output uses a filterless architecture, minimizing the number of external components and PCB
area while providing a high performance, simple and lower cost system. The PAM8014 also provides short circuit protection and thermal shutdown.
