1·With the dust cover closed and latched, the through connector interface has an IP65 rating thereby providing a watertight seal.
防尘盖封闭,锁存,通过连接器接口具有IP65防护等级,从而提供了一个水密封口。
3·The factors which will be encountered are descried and modules include anti-aliasing filter, clock circuit, band gap voltage reference, sc integrator, latched comparator and DAC are designed.
最后在考虑实际因素的基础上,依次设计了时钟产生电路、前置滤波器、带隙基准源、开关电容积分器、锁存比较器和DAC等子模块电路并做了仿真。
