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.

(1) Achievable output power levels are dependent on the thermal configuration of the target application. A high performance thermal interface material between the package exposed heatslug and the heat sink should be used to achieve high output power levels.

PMP10710 — 采用最佳升壓控制器的公告音頻參考設計

PMP10710 是一款可用于 100W +100W 立體聲或 200W 低音炮應用的 200W 公告音頻系統設計。此設計大致分為四個主要級：
  1. 采用 LM5122 控制器 IC 的單相同步升壓轉換器。此設計接受 10V 至 15VIN 輸入電壓（標稱為 12VIN），可實現 30V 輸出，并且能夠為負載提供 6.5A 連續電流。
  2. 采用 TAS5611 D 類器件的 100W + 100W 立體聲音頻放大器。
  3. 采用 OPA1632 差動放大器的針對立體聲輸入的單端至差動轉換（使用有源低通濾波器）。
  4. 使用 Simple Switcher LM16006 滿足所有輔助電源需求。
