TI中文支持网Part Number:BUF634AOther Parts Discussed in Thread:BUF634
BUF634应用场景如上图所示，在应用过程中发现BUF634器件经常损坏，测量BUF634输入输出引脚未发现异常高压；目前BUF634输入引脚添加了50欧姆的限流电阻；
请帮忙评估导致BUF634损坏的原因有哪些；50欧姆的输入限流电阻是否足够，运放的输入限流电阻应该如何计算；

您好，
您能否分享在设计中实施的原理图？ 输入端的50Ohm串联电阻不应导致任何问题,所以我不相信是这样。 设备在开机时是否出现故障，还是在驱动信号时出现故障？ 您能否分享通过电路驱动的信号以及负载条件(如果是)？ 有关所用耗材的任何信息也将是很好的信息。
