General Description
The AS621x is the second generation of the digital temperature sensor family, designed for high
accuracy applications with ultra-low power consumption. The new digital sensor design offers eight I²C
addresses and a supply voltage from 1.71V to 3.6V.
The AS621x family is a fully calibrated and linearized sensor system that is easy to integrate into any
digital system. It provides a 16-bit resolution over the full temperature range from -40°C to +125°C.
The integrated alarm functionality enables micro-controller wake-up calls at defined temperature
thresholds. An internal voltage regulator enables stable accuracy independent of the supply voltage.
For power sensitive applications, the device can enter a low-power wait mode with 0.1μA current
consumption.
