 value per second or even justget one sample on demand for power saving.
 Besides, it can completely power down its ADC, if power management is
 required.

+The ADT7420 is register compatible, the only differences being the package,
+a slightly narrower operating temperature range (-40°C to +150°C), and a
+better accuracy (0.25°C instead of 0.50°C.)
