采用 WCSP 封装的 25mW 立体声模拟输入耳机放大器

TPA6136A2（有时被称为 TPA6136）是一款 DirectPathTM 立体声头戴式耳机放大器，该器件免除了增设外部隔直流输出电容器的需要。 差动立体声输入和内置电阻设置器件增益，进一步减少了外部组件数。 可选增益为 0 dB 或 6 dB。 该放大器可从 2.3V 单电源为 16Ω 扬声器输送 25mW 的驱动功率。 TPA6136A2 (TPA6136) 提供了一个与电源电压无关的恒定最大输出功率，因而可简化防声震设计。 TPA6136A2 (TPA6136) 具有全差分输入和一个集成型低通滤波器，旨在减少音源与头戴式耳机放大器之间的系统噪声捡拾，并降低 DAC 带外噪声。 高电 • 专利 DirectPath 技术免除了增设隔直流电容器的需要 \n• 卓越的低频保真度\n• 喀嗒/噼啪噪声抑制活动\n• 电源电流通常为 2.1mA\n• 也可配置为单端输入\n• SGND 引脚可减少接地环路噪声\n• 简化了设计以防声震 \n• 可兼容 MicrosoftTM Windows VistaTM\n• 宽电源范围：2.3V 至 5.5V\n• 短路和过热保护\n• 提供小封装 \n• 16 焊球、1.6mm x 1.6mm、0.4mm 间距 WCSP;
