Product introduction

TAS5705 具有 EQ 和 DRC（s/w 控制）的 20W 立体声数字音频功率放大器

illustrate

该TAS5705是20瓦，高效率，数字化驱动立体声桥接式扬声器的音频功率放大器。两个串行数据输入允许处理多达四个分立的音频通道和无缝集成到大多数数字音频处理器和MPEG解码器。该器件接受的输入数据和时钟频率范围广。一个完全可编程的数据路径使这些渠道被路由至内部扬声器驱动器或通过线路电平PWM输出重低音扬声器或耳机输出。

该TAS5705是一个奴隶的唯一设备接收来自外部时钟。该TAS5705工作在384 kHz的开关速度为32 - ，48 - ，96 - ，和192 kHz的数据和44.1 -，88.2和176.4 kHz的数据352.8 kHz的开关频率。
