gpio to analog 0-5v

[mkgdkdk]

Hey.
I need too control are large power supply. It comes whit are analog 0-5v input.
Do anybody have are good way too convert the"digital" gpio output to are 0-5v output?

Could you post a link to the power supply you are trying to control?

Do you have a link to the specifications / documentation of the powersupply?

You man need as little as hooking up an SPI DAC such as:

MCP4901 (8 bit)
MCP4911 (10 bit)
MCP4921 (12 bit)

You may need some code to drive it.

Give a link to the power supply or data sheet.

Nice power supplies!

Says 0.2% accuracy for analog programming, so you want at least 9 bits for dac.

I'd use an MCP4921, 12 bits, pretty much the same price as the 10 bit one.

Good idea.
