Tiny device combines accelerometer and temperature sensor

A tiny 3-axis MEMS accelerometer, the LIS2DTW12 from STMicroelectronics embeds a temperature sensor that boasts typical accuracy of 0.8°C. The device’s thin 2×2×0.7-mm LGA-12 plastic package allows it to fit in space-constrained detectors such as wearables, shipping trackers, and IoT endpoints. Further, power consumption of just 50 nA in power-down mode and below 1 µA in active low-power mode extends battery runtimes.

Sixty-five different user modes enable developers to optimize power consumption and noise to meet application-specific requirements. The LIS2DTW12 offers user-selectable full-scale acceleration ranges of ±2 g, ±4 g, ±8 g, and ±16 g with output data rates from 1.6 Hz to 1600 Hz. Its embedded temperature sensor provides output data rates ranging from 50 Hz to 1.6 Hz and resolution from 8 bits to 12 bits.
