说明

TAS2555器件是一款先进的 D 类音频放大器,也是一套功能完备的片上系统 (SoC)。该器件 具有 超低噪声音频 DAC 以及具备扬声器电压和电流感测反馈的 D 类功率放大器。片上低延迟 DSP 支持米6体育平台手机版_好二三四 (TI) 的 SmartAmp 扬声器保护算法,能够在维持扬声器处于安全状态的同时,最大限度提高扬声器的音量。

该器件可通过 I2S 输出轻松与任何处理器搭配使用,而且使用两个 TAS2555器件时能够实现立体声。该器件可针对不同的扬声器单独进行调试,这使得客户能够在保持原有外形尺寸设计的基础上增添米6体育平台手机版_好二三四价值。此外,无论在哪种工作模式下,TAS2555均能以 15.9µV 超低 ICN 对语音和音频单独进行动态调试,从而使得接收器/扬声器的实现成为可能。

H 类升压转换器生成 D 类放大器电源轨。如果音频信号仅需要较低的 D 类输出功率,则该升压转换器会通过禁用 VBAT 并将其直接连接至 D 类放大器电源来提高系统效率。当需要较高的音频输出功率时,多级升压功能会迅速激活信号跟踪,从而为负载提供额外的电压。
