TAS5634 300W 立体声/600W 单声道高清数字输入、58V D 类放大器功率级 数据表 
TAS5634是一款PWM输入D类放大器功率级，可在58V标称电源电压下提供2 x 300W（6Ω）或1 x 600W（ 3 *）的输出功率.58V电源电压支持较高阻抗的扬声器负载，其中BTL为6Ω，PBTL为3Ω。集成式MOSFET和全新栅极驱动方案具有较高的峰值效率和较低的空闲损耗，能够减小散热器解决方案尺寸。
TAS5634使用闭环反馈设计，具有恒定的电压增益。开关模式电源（SMPS）的使用，使得内部匹配的增益电阻器可确保实现较高的电源抑制比较（PSRR）和较低的输出噪声。
TAS5634是一款兼容TI的数字输入（I2S）音频处理器和调制器产品组合的全集成式功率级，与TAS5548和TAS5558类似，也是一个完整的数字输入D类放大器.TAS5634采用表面安装44引脚HTSSOP封装，是PWM输入D类功率级兼容引脚产品系列（包括TAS5612LA，TAS5614LA和TAS5624A）中的一员
