Digital temperature sensors have low-power wait mode

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 linearised 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.

Applications for the sensors include high accuracy consumer electronics, mobile devices/tablets/notebooks, wearables/mobile health, cameras, HVAC and thermostat control, cold chain monitoring, industrial automation, lab equipment, and Solid State Drives (SSD).
