The outflow current at pin @ should preferably be 10014, or less, but it should be noted that if it is 10A or less, it is vulnerable to the influence of noise. If the current is determined independently of the horizontal frequency, connect pin @ at constant current as shown below or 12009 oe insert a resistor across the earth in parallel to external ; capacitance of each timing pin with pin @ open. In this ] case, the usage is quite the same as in pin @. 2)F to V converting filter (pin @) This filter is used for M/M output smoothing, which is set for 10V and OV at duty 100% and 0% respectively. The larger the capacitance is, the better it is so long as the response at the unit side is allowed. 3)F to V conversion output (pin @) The same voltage as pin @ voltage is output with the —2)H-Phase (Pin @) buffer. However, since the D range of buffer amplifier When pin @ voltage is 9V or more, 100% of pin D input (pin @) exceeds 1.5Voc, it is necessary to set a current becomes effective, and the delay amount is the resistor and capacitor on pin @ so that pin @ voltage smallest.
