    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

    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?
