voltage conversion circuit composed of NJM4558


Posted on Feb 5, 2014

Figure 1-42 (a) is a voltage / current conversion circuit, and it can convert 0-lOV input voltage into 4-2OmA output current. Adjusting RP2 could make Ui = 0, I. = 2OmA; adjusting RP2 could make Ui = lOV, I. = 4mA. Figure 1-42 (b) is the current / voltage conversion circuit, which will convert the 4-2OmA current into -10 to + lOV output voltage. Adjusting RP..
