TAS2560是一款低功耗,高性能,数字输入升压D类音频放大器,可轻松实现单声道和立体声(x2)应用。该器件具有超低噪声音频DAC和D类功率放大器,其中整合的扬声器电压和电流感测反馈用于扬声器保护算法。
H类升压转换器生成D类放大器电源轨当前音频信号只需要较低的D类输出功率时,可通过禁用升压并将VBAT直连D类放大器电源来提升系统效率。当需要较高的音频输出功率时,多级升压功能会重新激活信号跟踪,从而为负载提供额外的电压。
可配置的片上电池保护系统可降低电池电压过低期间的音频输出功率,从而尽量防止电池电压下降到系统欠压条件以下。此外,欠压,过流和过热等故障可使用IRQ引脚报告回主机处理器。通过读取寄存器可获得所有保护状态。
