I am working on a system that will drive a piezoelectric inkjet head. A microcontroller and a digital-to-analog converter is being used to produce a controlled pulse shape (a specific rise time, hold time, and fall time).
This pulse then needs to be amplified from 5 volts to the 15 to 30 volt range. The pulses will have rise and fall times in the 1 us to 20 us range.
I have seen a solution that uses the Apex line of high voltage/high slew rate opamps but I think those might be over kill and I am looking for something cheaper.
Does anyone have any implementation suggestions?
Sincerely, James McMillan
