RT9121 是採用 I<sup>2</sup>S 介面的高效身歷聲音訊功率放大器，推動 BTL 連接的 8Ω 揚聲器時能輸出最大 2x30W 的功率，電能轉化效率可達 94%，無需使用散熱元件，內含過熱保護、過流保護、過壓保護、直流和欠壓保護及故障報告功能。</br>RT9121 屬於 I<sup>2</sup>S 器件，通過接收外來時鐘驅動其工作。它可支援 Master 和 Slave 兩種模式，輸入信號的取樣速率範圍為 8kHz-192kHz，其內含資料通道完全可程式控制，最終將資料引導至揚聲器驅動電路。</br>RT9121 包含三段 DRC 和靈活的多段四邊濾波器，可消除暴烈聲，對輸出功率進行限制，實現揚聲器均衡。
