TPA3131D2

支持无滤波器操作的 4W 立体声、8W 单声道、4.5V 至 26V 电源电压、模拟输入 D 类音频放大器

TPA313xD2 是用于驱动扬声器的高效立体声数字放大器功率级,峰值驱动功率高达 2x42W/4Ω。 TPA3131/32D2 的印刷电路板 (PCB) 通过底部 PowerPAD 进行散热,无需使用散热器,同时可持续提供 2 × 4W/8Ω (TPA3131D2) 至 2 × 25W/8Ω (TPA3132D2) 范围内的输出功率。TPA313xD2 高级振荡器/PLL 电路采用多开关频率选项来抑制 AM 干扰;搭配使用主从模式同步选项时,还可使多个器件实现同步。TPA313xD2 针对短路、过热、过压、欠压和直流等故障提供了全面保护。 在过载情况下,器件会将故障情况报告给处理器,从而避免 • 支持多种输出配置 \n• 19V 电压、8Ω BTL 负载条件下的功率为 2 × 25W (TPA3132D2)\n• 宽电压范围:4.5V 至 26V\n• 高效 D 类运行 \n• 高级调制系统配置\n• 多重开关频率 \n• 主从模式同步\n• 采用具有高 PSRR 的反馈功率级架构,降低了 PSU 需求\n• 差分和单端输入\n• 由单电源供电运行,减少了元件数量\n• 散热增强型封装 \n• -40°C 至 85°C 环境温度范围;
