RT9120H 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 (Bridge Tied Load) 扬声器负载提供最大 2x50W 输出。它可在 2x10W 时提供超过 94% 的功率效率，免除散热片需求，并实作 CMH 模式以在小讯号时降低脉冲宽度，进而减少电感电流涟波并提升轻载效率。内建防爆音功能可在各种情境下降低扬声器的爆音杂讯。内建保护电路可提供过温、过电流、过压与欠压保护，并回报错误状态。RT9120H 是一款 3 线式元件，可从外部来源接收所有时脉，并支援标准 I<sup>2</sup>S、左对齐、右对齐或 TDM (Time-Division Multiplexing) 格式。它可支援 8kHz 至 192kHz 的宽输入取样率。RT9120H 具备单频带 DRC (Dynamic Range Compression)、弹性输入混音器与功率削波功能。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。
