TL431中文手册 TL431, A, B集成电路是二端可编程井联稳压一极管。这些单片集成电路电压基准如同低温度系数齐纳管一样运行,通过2个外部电阻可从Vref编程至36伏。这些器件显示出宽工作电流范围,在典型动态阻抗0.2252时为1.0毫安至100毫安。这些基准的特性使他们能在数字电压表、电源和运放电路等许多应用中代替齐纳一极管。2.5伏参考使从5.0伏逻辑电源可力一便地获得稳定参考电压。由于TL431, A, B工作方式为并联稳压器,所以可以用作正压或负压参考。
The MAX4080/MAX4081 are high-side, current-sense amplifiers with an input voltage range that extends from 4.5V to 76V making them ideal for telecom, automotive, backplane, and other systems where high-voltage current monitoring is critical. The MAX4
