数据: TAS575xL Digital-Input, Closed-Loop, Class-D Amplifier 数据表
TAS5754M器件是一款高性能立体声闭环放大器,集成了带PurePath™HybridFlow架构的音频处理器。为了从数字转换为模拟,它采用了具有Burr-Brown混合信号传统的高性能DAC。它只需要两个电源:一个用于低压电路的DVDD和一个用于高压电路的PVDD。它通过使用标准I²C通信的软件控制端口进行控制。在该系列中,TAS5756M采用传统的BD调制,确保低失真特性。 TAS5754M采用1SPW调制,以略高的失真为代价降低空闲电流消耗。
独特的HybridFlow架构允许系统设计人员从多个可配置的DSP程序中进行选择,专门设计用于流行的音频端蓝牙(BT)扬声器,条形音箱,扩展坞,低音炮等设备。这将完全可编程器件的灵活性与快速下载时间和固定功能ROM器件的易用性相结合。
90mΩr提供了热性能和器件成本的最佳组合。 >输出MOSFET的DS(ON)。此外,热增强型48端子TSSOP可在现代消费电子设备的高温环境下提供出色的操作。
