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 — 采用一流升压控制器的公告音频参考设计
PMP10710 是一种 200W 设计、适用于公共广播的音频系统，可用于 100W + 100W 立体声或 200W 低音扬声器应用。设计大致分为四个主要阶段：
- 使用 LM5122 控制器 IC 的单相同步升压转换器。 此设计的输入电压范围为 10V 至 15VIN（标称 12VIN），可提供 30V 输出电压，能够为负载提供 6.5A 的连续电流。
- 使用 TAS5611 D 类器件的 100W + 100W 立体声音频放大器。
- 使用 OPA1632 差分放大器、用于立体声输入的单端到差分转换（采用低通滤波器）。
- Simple Switcher LM16006 可满足所有辅助电源需求。
