USAGE EXAMPLE (set-up section)
There is a single VCC powered DS2450 on the 1-Wire bus. Set-up channel D for 12 bits, 5.12V range and
alarm thresholds of 2.0V (64h) and 3.0V (96h) (increment 20 mV) and convert the input voltage; turn on
the channel A output if low alarm occurs and the channel B output if high alarm occurs, respectively.
