I have an 3 phase ac inverter that uses standard potentiometer for motor speed regulation. enter image description here

The speed reference voltage is 0-10v and i need to control it using arduino. In MCP41010 datasheet I couldn't find the maximum voltage between the potentiometer pins only the supply voltage. Has anyone got experience with this digital potentiometer and if it's possible to be used here?

It's a bit sneaky, but it's there (Section 1.0 Electrical Characteristics):

Resistor Terminals
Voltage Range \$V_{A,B,W}\$: Min 0, Max \$V_{DD}\$

Doesn't seem like it's appropriate for your application.

  • \$\begingroup\$ Thanks. Too bad it was the only available pot i could find here, I'll probably wait a month to get compatible one from ebay \$\endgroup\$ – JcOaCrO Feb 5 '16 at 1:08
