TAS5612A - 125 W 立体声/250W 单声道 PurePath? HD 数字输入功率级 - 无 - 中/高功率D类放大器 - TI公司（Texas Instruments，德州仪器）
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.
