Other Parts Discussed in Thread: THS1408 I use THS1408 which have powerpad in my project,when I want to layout, I confused with connect of powerpad,In the datasheet and SLMA002 , Just say the pad should connect to internal layer with via,But the internal…
Other Parts Discussed in Thread: THS1408THS1408的差分输入端单端输入电压范围手册上是-0.3V~+3.6V,双端输入电压范围是+-2V。我们现在电路的设计是将+端接+1.6V参考电压,负端输入模拟信号经钳位二极管接地和+3.3V电源保护。由于前端模拟电路上电时一段时间处于未定状态,THS1408经钳位二极管保护后的输入电压最高在+4V,最低在0.7V。尽管目前用下来没问题,但因为超过了手册上的Absolute Ratings,不知道这样用对器件是否有损害…
