Hi,
I want to suppy square wave (5v and 0 volt) to OPA547 and I want to control the Output Voltage and Output Current. Before applying this square wave, first I try to put DC battery (in MULTISIM Simulation). I calculate the Rcl and gain so that I can know the range resistor used. I also put 50 ohm as Rload. With this load when I start to simulate, after 100 ms, the voltage increase little bit and the current drop significantly. But if I put smaller Rload (18 or 20 ohm), it is fine. Is there any steps I missed ?
oh ya, I use 8 volt power supply and ground (one supply).
Note :
My target is 80 mA and 6 volt for output (for infrared sensor power
