STMicroelectronics LIS2DW12 3-axis accelerometer

STMicroelectronics’ LIS2DW12 3-axis accelerometer delivers flexibility and energy savings by supporting multiple low-power and low-noise settings in a 2 x 2 x 0.7 mm package.

The product has 16-bit output and can be set to prioritise low power consumption or low-noise performance, with five settings in either mode. A specific feature coupled with four settings in each mode saves waking the system to check for data and allows efficient single-byte transfers, further minimising system power consumption and helping extend battery life. Noise density down to 90 µg/√Hz is said to be 25% lower than similar devices in the marketplace, which improves the measurement accuracy in next-gen applications from health care, fitness and gaming to industrial sensing and environmental monitoring.

Drawing as little as 50 nA in standby, or 380 nA in low-power mode at 1.6 Hz output data rate, the device adds negligible load on the battery. The supply-voltage range of 1.62 to 3.6 V allows extended operation from small coin or button cells. Features that support system-level power savings include a 32-bit output FIFO, a built-in temperature sensor, a programmable interrupt for freefall, wake up, activity/inactivity, 6D/4D orientation detection and tap/double-tap detection.
