Description

ams AS621x Digital Temperature Sensors are the second generation of the digital temperature sensor family. These devices are designed for high accuracy applications with ultra-low power consumption. The new 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. The device 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.
