USB ADC/DACs

Hello,

 

Based on feedback I got at the beam and instrumentation workshop this week I am trying to come up with a simple and cheap design to control analog power supplies. Nothing is set in stone and I just want to find what we would need to get to make this controller. I am trying to find a DAC/ADC that can be connected using USB to a soft-ioc running linux. I don’t need a lot of channels, 1 analog in and 1 analog out would be fine (2 of each would be preferred) and having a couple digital in/digital out channels would be nice too (but not required). The voltage will be 0-10V (if a bipolar DAC/ADC is available that would be great). I would probably need to have at least 16 bits of resolution on the DAC/ADC. The speed doesn’t have to be terribly fast from what I gathered. Cost is an issue (trying to stay under $200) but if something is out there that costs more than this I would like to take a look at it anyway.

 

I wonder if anyone in the epics community has worked with such a device and if they have epics drivers available. If epics drivers aren’t available I can probably configure something myself using ASYN if someone can point me to a good reliable device. Any suggestions would be greatly appreciated, thank you.
