PAM8303C Description:大象配资

PAM8303C是一款3W单声道无滤波器d类放大器，具有高PSRR和差分输入，可消除噪声和射频整流。90%的效率和较小的PCB面积使PAM8303C d类放大器成为手机的理想选择。无滤波器架构不需要外部输出滤波器，更少的外部元件，更少的PCB面积，更低的系统成本。无过滤器架构也简化了应用程序设计。PAM8303C具有短路保护和热关闭功能。PAM8303C提供MSOP-8和U-DFN3030-8封装。

The PAM8303C is a 3W mono, filterless Class-D amplifier with high PSRR and differential input that eliminate noise and RF rectification.Features like 90% efficiency and small PCB area make the PAM8303C Class-D amplifier ideal for cellular handsets. The filterless architecture requires no external output filter, fewer external components, less PCB area, and lower system costs. The filterless architecture also simplifies application design. The PAM8303C features short-circuit protection and thermal shutdown. The PAM8303C is available in MSOP-8 and U-DFN3030-8 packages.
