Electronics I need an digital potentiometer

I'm looking for a digital potentiometer

like this one
http://products.analog.com/products/info.asp?product=AD5201

but one I could control with a computer com port



does someone know where I can find this



thanks

 

Just buy a D2A (digital to analog) converter and use it with a variable voltage regulator for high loads. Most (if not all) digital pots can sink only a few microamps, it's a waste to try to put a load on them. They are only good for reference voltages.

thanks for your help


can you tell me wich D2A I should use?
I know a few things in electronics, but absolutely nothing about digital and com port communication
