The TAS5611A is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 125W(1) Stereo into 4 to 8 Ω Speakers from a single 32.5V supply.
PurePath™ HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers.
Unlike traditional Class D amplifiers, the distortion curve only increases once the output levels move into clipping.
PurePath™ HD technology enables lower idle losses making the device even more efficient.

PMP10710 — 運用同級最佳升壓控制器的公開音訊參考設計
PMP10710 是一款用於公共廣播音訊系統的 200W 設計，可用於 100W + 100W 立體聲或 200W 低音揚聲器應用。本設計大致分為四個主要階段：
- 採用 LM5122 控制器 IC 的單相同步升壓轉換器。 此設計接受 10V 至 15VIN 的輸入電壓（額定 12VIN），並提供 30V 的輸出，可為負載提供 6.5A 連續電流。
- 使用 TAS5611 D 類裝置的 100W + 100W 立體聲音訊放大器。
- 立體聲輸入使用 OPA1632 差動放大器的單端至差動轉換（具主動低通濾波器）。
- Simple Switcher LM16006 用於滿足所有輔助電源需求。
