Intro
ATTENTION: The user must provide an external circuit
to ignore the analog output signal for two seconds after
power-up. After reset the analog output may be in an inde-
terminate state for a short period before it stabilizes at the
software controlled setting. Failure to observe this precau-
tion could result in severe bodily injury.
