  • Product introduction

TAS5704  具有 EQ、DRC 和反馈(硬件控制)的 20W 立体声数字音频功率放大器

illustrate

 

该TAS5704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接受的输入数据和时钟频率范围广泛的音频处理器。 一个硬件配置的数据通道使这些渠道被路由至内部扬声器驱动器或通过PWM输出重低音输出。

该TAS5704是一个奴隶的唯一设备接收来自外部来源的所有时钟。 该TAS5704工作在384 kHz的开关速度为32 - ,48 - ,96 - ,和192 kHz的数据,并以352.8 kHz开关为44.1 -,88.2 -和176.4 kHz的数据传输速率。 8 × sampling combined with a fourth-order noise shaper provides a noise floor in units from 20 Hz and an excellent dynamic range of 20 kHz.
