[sdiy] DVMs as A to D's

[James Patchell]

If you need a high resolution A-D converter, I wouldn't bother with a 
DVM...a 3-1/2 digit DVM is barely 12 bits...I would get a Crystal 
Semiconductor CS 5540 delta sigma converter.  It converts two channels at 
about 5 samples/second...and it is 24 bits.  I am using one of these at 
work right now...real cool part.
