somewhat a novice at this, so please excuse the evidence.
I have a digital to analog card that produces a maximum of 0 to 10V with a maximum current output of 2mA. This signal is coming from a digital function generator that allows the user to create various pulse trains. The signal is going into a non-inverting opAmp circuit used to double the voltage at the final terminals. The resulting voltage is from 0 to 20 volts open loop depending on the orginal signal from the D/A card. I have a load of approximately 45 Ohms, which when connected across the opAmp terminals, drops my voltage down to 1V. I need to deliver from 0 to 25mA to my device.
1: can I use some sort of capacitive circuit to increase the final current delivered to my device.
2: am I in over my head or does this sound fairly approachable for a novice?
Does anyone have a suggestion for an alternate method of meeting my device objectives?
Thanks in advance, alan.
