RT9125 是一款高效率、I<sup>2</sup>S 输入、立体声通道音讯功率放大器，可向 8Ω BTL 扬声器负载提供 2x30W 输出。它可提供超过 94% 的功率效率，并免除散热片需求。内建保护电路可提供过温、过电流、过压、DC 与欠压保护，并回报错误状态。RT9125 是一款 I<sup>2</sup>S 元件，可从外部来源接收所有时脉。完全可程式化的资料路径可将这些通道路由至内部扬声器驱动器。RT9125 具备三频带 DRC 与弹性多频带 biquads，可用于防削波、功率限制与扬声器等化。建议接面温度范围为 −40°C 至 150°C，环境温度范围为 −40°C 至 85°C。
