Hi,
I bought an AC piezo driver (0-20V, bandwidth>100kHz).
I also have a DC piezo driver (0-150V).
I want to build something that can add those two signals.
I tried to use a high-power, ultra-fast OpAmp to make a simple adder.
The problem I got so far is that the rising time is killed when I
connect the piezo (C=600nF). I need a rising time of less than 10us for
Vpp=20V.
The other problem with this design is that the 2 drivers output are not
isolated from each other.
Does anyone has an idea on how I can solve my problem.
Does anyone know good reference (book, web site...) to build piezo
drivers.
Thank you very much for your help.
