I want to control a hydraulic valve which accepts a variable voltage from 0V to 12V. That's easy enough with a DAC, but I'm not sure what load I can drive with a DAC. Unfortunately it's not easy getting your hands on data sheets for hydraulic valves so I'm not sure what current will be required by the solenoid. I've sent a question to the maker and hopefully they'll provide the specs.
Mean time I thought I'd try to find out more. How do you drive a load from a DAC? I've looked over a few DAC data sheets and they don't seem to specify the load that they can drive. If they DAC only drives a limited load how do you get a higher load? I know there is a Current mirror but is there a similar mechanism for Voltage?
