386D音频功率放大器主要应用于低电压消费类产品。
为使外围元件最少，电压增益内置为20。
但是在1脚和8脚之间增加一只外接的电阻和电容，便可将电压增益调为任意值，直至200。
输入端以地为参考，同时输出端被自动偏置到电源电压的一半。
在6V电源电压下，它的静态功耗仅为24mW，使得386D特别适合于电池供电的场合。
386D的封装形式为DIP8特点：z静态功耗低，约为4mA，可用电池供电z电压增益由20~200可调z电源电压范围宽，Vcc=4~12Vz外围元件少z失真度低应用范围zAM/FM收音机音频放大器z线驱动器z便携式录音机音频功率放大器z超声波驱动器z免提电话机扬声系统z小型伺服驱动器z电视机音频系统z电源变换器

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
