3-axis accelerometer for consumer and industrial devices measures ±18g

September 02, 2013 // By Graham Prophet
STMicroelectronics’ latest high-performance 3-axis MEMS accelerometer, the LIS344AHH, enhances gaming, user-interface and augmented reality experiences, as well as industrial controls and impact monitoring, by providing a large full-scale range of up to ±18g combined with high bandwidth, low noise, and high mechanical and thermal stability.

The high bandwidth of the new device permits a high output data rate allowing sustained accurate measurement of rapidly changing accelerations, enabling enhanced industrial controls, robotic equipment and wearable electronics such as sports monitors. Combining high data rate with low-noise operation that enables monitoring of small-amplitude displacements, this accelerometer delivers, ST says, smoother, more responsive performance in motion-activated controls and also supports more demanding applications such as virtual augmented reality.

The LIS344AHH full-scale range is user-selectable up to ±6g or ±18g, enhancing performance over similar devices that measure up to ±16g. The device has a supply voltage range of 2.4V to 3.6V, features embedded self-test, and is housed in a compact 4 x 4 x 1.5 mm 16-lead LGA-16 package. I costs $8.40 (1,000).
