AD694JN是一个单片电流变送器接受高层次的信号输入到阀,控制标准4-20 mA电流环驱动执行器,并广泛应用于过程控制其他设备。输入信号是由一个缓冲输入放大器,可用于大规模的输入信号或缓冲区从一个电流模式DAC输出。把输入跨度为0 V至2 V和0 V至10 V是由简单的引脚捆扎选择;其他跨上可以与外部编程电阻。
The AD694 is a monolithic current tran***itter that accepts high level signal inputs to drive a standard 4-20 mA current loop for the control of valves, actuators, and other devices commonly used in process control. The input signal is buffered by an input amplifier that can be used to scale the input signal or buffer the output from a current mode DAC. Precalibrated input spans of 0V to 2V and 0V to 10V are selected by simple pin strapping; other spans may be programmed with external resistor.
