3 说明

TAS5558 是一款具有数字音频处理功能和采样率转换器的 8 通道数字脉宽调制器 (PWM),具备先进的性能和较高的系统集成度。 TAS5558被设计用于支持 DTS-HD 规格蓝光 HTiB 应用。 ASRC 包含两个独立的模块,每个模块可处理 4 个通道。 因此,它能够支持多达两个不同的输入采样率。

米6体育平台手机版_好二三四 (TI) 功率级设计用于与 TAS5558 无缝配合工作。 TAS5558还提供一个高性能、差分输出以驱动一个外部、差分输入、模拟头戴式耳机放大器。

针对 48,96 和 192kHz 数据,TAS5558支持开关速率为 384kHz 的 AD,BD 和三重调制。 必须采用频率为 12.288MHz 的外部晶振。 TAS5558 还具备电源容量控制 (PSVC) 功能,可增大低功率级的动态范围,并且在与闭环 PWM 输入功率级一起使用时,可作为 G 类电源的一部分。
