作为一个扩展到额定电压的绝对最大额定值部分tas5111，tas5112，TAS5121和tas5122本应用笔记给出了一个数据表更明确的描述的峰值电压与时间的最大限制在BST和销。此外，测量技术和测试设置描述和如何避免超过设备电压的应用程序设计指南定义为包络曲线的限制。
Introduction
TAS5111， TAS5112， TAS5121 and TAS5122 devices are all Class-D amplifier output stages designed to provide high-power output at high efficiency and low harmonic distortion. As typically seen in high-speed power devices the voltage potential on specific pins swing high （and low） with very large dv/dt leaving artifacts that it are important to consider while designing the environment （i.e.， PCB and external components） for the power stage device.
The issue addressed in this apps note， in particular， is the voltage overshoot that is likely to occur when current is flowing into a half-bridge during a low-to-high transition.
