Matt Nelsen (min0130@tam2000.tamu.edu) tried out:
: Hello,
:     Is there any such thing as a digital voltage regulator?  I was thinking
: something along the lines of an IC with 4, 8, or 16 inputs (or even better,
: an internal register of same sizes)  that could produce as output one line
: with 16, 256, or 65536 discrete voltages respectively.  Can anyone help?
: Thank you.  Later!

Sounds like what we *usually* call a D/A converter, possibly with a pass
transistor to boost the current.  a 4/8/16 bit one would do the steps above.
Most of the chip manufacturers make 'em, with a profusion of features or
warts.  You can even get 'em with serial ports instead of the parallel (port
waster) interface, but the response speed goes down by at least 10 'cos you
have to have time to send all the bits serially.

Time to hit the data books.... or the Harris web site (www.semi.harris.com).
The path you'll want to look down will mention `Data Acquisition', probably.
