4-20mA单芯片电流发射器

AD694是一款单芯片电流发射器，可接受高电平信号输入以驱动标准4-20 mA电流环路，从而控制过程控制中常用的阀门、执行器和其它设备。输入信号由一个输入放大器缓冲，可以利用该放大器调整输入信号或者缓冲一个电流模式DAC的输出。通过简单的引脚绑定可以选择预校准的0 V至2 V或0 V至10 V输入范围；其它范围可以通过外部电阻进行设置。\n\n 输出级电源电压可以达到VS的2 V范围内；采用双电源工作时，其特殊设计允许输出电压低于共模电压。4-20 mA环路开路或输出级不符合要求时会发出报警。\n\n 经过有源激光调整的薄膜电阻使AD694具备高精度特性，无需执行额外调整和 • 输出范围：4-20 mA、0-20 mA \n\n• 预校准输入范围：0V至2V、0V至10V \n\n• 精密基准电压可编程至2.000 V或10.000 V \n\n• 单电源或双电源供电\n\n• 宽电源电压范围：4.5V至36V;
