Note 4:
Temperature stability for the LM336 and LM236 family is guaranteed by design. Design limits are guaranteed (but not 100% production tested) over the
indicated temperature and supply voltage ranges. These limits are not used to calculate outgoing quality levels. Stability is defined as the maximum change in V
物联网是新一代信息技术的重要组成部分，也是“信息化”时代的重要发展阶段。其英文名称是：“Internet of things(IoT)”。顾名思义，物联网就是物物相连的互联网。这有两层意思：其一，物联网的核心和基础仍然是互联网，是在互联网基础上的延伸和扩展的网络;其二，其用户端延伸和扩展到了任何物品与物品之间，进行信息交换和通信，也就是物物相息。下面就随嵌入式小编一起来了解一下相关内容吧。 下...[详细]
在体验 Pixel 6 Pro 的这段时间里，除了拍照，我很少有感觉到这台被 Google 称作‘最聪明的 Pixel 手机’有什么过机之处，直到一个早上，手机闹钟把我吵醒。 和普通手机滑动关闭闹钟的操作不同，Pixel 6 Pro 提示我可以说‘Snooze（再歇一会）’或者‘Stop（停止）’来控制闹钟，而当我小心翼翼地说出‘Stop’后，闹个不停的手机果然立刻安静了下来。 ...[详细]
