I need to control a lighting fixture with a 0-10v dimming level input.
This dimming level is set by a a micro controller which has I2C output.
I was thinking of controlling the output via a DAC with an I2C input. Either I need to find a DAC that can output 10V or use an op amp stage (following the DAC) to level shift the signal.
Are there any other circuit ideas I've overlooked ?
