数据: TAS5727 25-W Digital Audio Power Amplifier With EQ and DRC 数据表
TAS5727是一款25瓦,高效的数字音频功率放大器,用于驱动立体声桥接扬声器。一个串行数据输入允许处理多达两个离散音频通道,并与大多数数字音频处理器和MPEG解码器无缝集成。该器件可接受各种输入数据和数据速率。完全可编程的数据路径将这些通道路由到内部扬声器驱动器。
TAS5727是一个仅从设备,接收来自外部源的所有时钟。 TAS5727采用PWM载波工作,开关速率为384 kHz,开关速率为288-KHz,具体取决于输入采样速率。过采样与四阶噪声整形器相结合,可提供平坦的本底噪声和20 Hz至20 kHz的出色动态范围。
