Motion sensor offers low-power settings
The MEMS device provides 16-bit output and can be set to prioritize low power consumption or low-noise performance, with a choice of five settings in either mode. According to the manufacturer, the sensor’s noise density of down to 90 µg/√Hz is 25% lower than similar devices in the marketplace, which improves measurement accuracy in a wide range of healthcare, fitness, gaming, industrial, and environmental applications.
The LIS2DW12 has user-selectable full-scale ranges of ±2 g, ±4 g, ±8 g, and ±16 g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz. Other features include an embedded self-test capability, an integrated 32-level FIFO, a built-in temperature sensor, and a programmable interrupt for freefall, wake up, activity/inactivity, 6-D/4-D orientation detection, and tap/double-tap detection.
Engineering samples of the LIS2DW12 are available now, with volume production to begin in Q1 2017. Prices for the accelerometer housed in a 2×2×0.7-mm LGA package start at $0.75 in lots of 1000 units.
