TFA9882UK: 3.4 W I2S输入单声道D类音频放大器

TFA9882是单声道无滤波器D类音频放大器,采用9凸块WLCSP(晶圆级芯片封装),具有400 µm的间距。

该器件通过I²S数字接口接收音频和控制设置。掉电模式到工作模式的转换在位时钟输入(BCK)上检测到时钟信号时触发。两个器件可以组合起来构建立体声应用。

在立体声应用中,左或右I²S音频流通过将字选择信号分别连接到针脚WSL或针脚WSR进行选择。单声道混合可以通过将字选择信号同时连接到WSL和WSR而实现。关闭字选择信号即选择静音模式。

该器件具有低RF敏感度,因为它具有对时钟抖动不敏感的数字输入接口。TFA9882中使用的二阶闭环结构提供了出色的音频性能和高电源电压纹波抑制。
