Lynn,

That is a cool device.  I had never heard of that before.

Thanks,

Terry,

I have not driven one of these from a D/A converter, but I have often done this with op amps. I have built current regulators this way. 

These devices are robust: So long as you do not put too much voltage (>35 V) on the inputs or omit the required bypass capacitors, they are nearly impossible to destroy by shorting: They just shut down.  They are also quite inexpensive and readily available.

With an inductive load like the solenoid, some protective diodes are also recommended.
