PAM8014 Description:
PAM8014是一款3.2W无单声道滤波器D类放大器，具有高PSRR和差分输入，可消除噪声和RF整流。效率超过90%和PCB面积小等特点使PAM8014 D类放大器成为便携式应用的理想选择。
PAM8014具有短路保护和热关断功能。PAM8014采用U-WLB1313-9封装。 The PAM8014 is a 3.2W mono filter-less class-D amplifier with high PSRR and differential input that eliminate noise and RF rectification. Features like greater than 90% efficiency and small PCB area make the PAM8014 Class-D amplifier ideal for portable applications. The output uses a filter-less architecture, minimizing the number of external components and PCB area whilst providing a high performance, simple, and lower cost system.
The PAM8014 features short circuit protection and thermal shutdown.The PAM8014 is available in the U-WLB1313-9 package.
