Hello, I would like to use the MCP41010 to digitally control from arduino a DC/DC StepUp converter.
I have read the datasheet https://ww1.microchip.com/downloads/en/DeviceDoc/11195c.pdf , but maybe I miss something.

My question is, that the voltage accross the potentiometer the dc/dc converter has reaches 32 V.

can the Digital pot stand that voltage or it will be destroyed ?
Can you suggest me some solution ?
Thank you

Unable to understand the exact meaning of this sentence. MCP41010 is a 5V part, so ist's power supply and voltage on any pin shouldn't be above 5V by design (7V absolute maximum rating). The question refers to your (yet unknown) circuit.
 
My question is
Can I use this digital potentiometer to control voltages greater than 5v?
 

You have to use an OpAmp to amplify the 5V to 0V the device gives as shown in page 15 but I don't know whether the Op-Amp shown in page 15 can do that. Use any Op-Amp that works at 48V.
 
Thank you for the replies. That gets too complicated and will take lots of time and testing. I will use servo potentiometer for best results!
