Update on this:? I did put together a battery and
voltage
divider to test the AXV11.? The label on the A/D module
says it brings the output from the multiplexer to one of
the external pins.? I was able to verify that the voltage
applied to a couple of the A/D inputs makes it through the
multiplexer when selected using the CSR.? The next output
available is from the Sample and Hold, and this is always
pegged at +12v.? Am I wrong to assume that the sample and
hold will 'freeze' its output when the A/D go bit is set?
Well, it will probably only hold the approximate voltage for
a few seconds, but should be long enough to see on a voltmeter.
