Product introduction

TPA2005D1-Q1 汽车类 1.4W 单声道无滤波 D 类音频功率放大器

illustrate

该TPA2005D1是1.4 W高效率的无滤波器D类采用QFN或MSOP封装的音频功率放大器，只需要三个外部元件。

效率的功能，如84％，- 71 - dB的PSRR在217赫兹，提高了射频整流免疫力和15平方^millimetre的PCB面积使手机TPA2005D1的理想选择。一个快速启动的9毫秒的时间以最小的流行使得对PDA应用TPA2005D1的理想选择。

在蜂窝电话，听筒，免提电话，和旋律铃声可分别驱动的TPA2005D1。该器件还允许48μV的_有效值独立增益控制的信号求和从每个功能，同时最大限度地减少噪音而已。
