的完整性,因此有着极好的可靠性和高频瞬态抑制特性。放大器和栅电容一同密封在DIP内。ISO120与ISO121的差异仅在于封装尺寸和额定隔离电压上。这些放大器使用方便,无需外部元件就可获得60kHz的带宽

。若附加使用两个外部电容器,则可保证在6kHz带宽内有精密额定0.01%的非线性度(最大值)和150μV/°C (最大值)的Vos漂移。ISO120/121的电源供电范围为±4.5~±18V,具有低的静态电流。

ISO124应该可以传送直流信号吧? 为什么ISO120那么贵? 跟ISO124相差那么多?

哪位大神有ISO14443A的头文件?即ISO14443a.h.

我想选用ISO7721用于485隔离,遇到带你问题,请帮忙看看。 ①看到PDF上描述IIH(High-level input current)最大到10uA,但是MCU SCI TX引脚输出一般
