TAS5830 电源与音频指标:闭环 D 类报告
The manufacturer datasheet lists peak stereo power up to 65 W with reported efficiency greater than 90% and THD+N as low as 0.03% at 1 W. This report explains how to test, interpret, and optimize TAS5830DADR performance for real-world audio designs. TAS5830 Overview & Closed-Loop Fundamentals Closed-loop Class-D topology centers on applying feedback to deliver consistent power into reactive loads. Unlike open-loop designs, the feedback loop reduces THD under varying speaker impedance and compensates for supply sag, requiring careful PCB layout and loop compensation. TAS5830 IC I2S IN OUT_A OUT…
