Hi,
I am using a pa240cc (http://media.digikey.com/pdf/Data Sheets/Cirrus Logic PDFs/PA240.pdf) to amplify an input signal that is between 0 to 10 volts and map it to 0 to 100 V.
The amplification seems to work fine. however when a triangle wave is fed to the input the output looks like a sine wave. when i sine wave is fed to the input the out put is still sinusoidal however it is a bit distorted and it is phase shifted. Also the input frequency at 1kHz for both of these observations. I have attached the schematic for the circuit I'm using:
I suspect it might be some sort of compensation that i need to do however I am not an electrical engineer so I'm not sure how to go about resolving the problem. I've tried googling the issue but I'm not sure what keyword to use for the search. Any suggestions or tips are much appreciated.
Thanks.
Edit: I forgot to mention the supply voltage is 150 V measured from +VS to ground
