TAS5612A数据手册TI中文资料规格书

描述 Description

The TAS5612A is a high performance digital input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 125W 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. 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.
