STmicroelectronics LIS302ALK: Accelerometer gauges values on three axes

Joining the vendor’s family of ultracompact low-g linear accelerometers, the LIS302ALK axis accelerometer measures acceleration values for the x, y, and z axes. The low-power MEMS (microelectromechanical-system) device provides an analog output, with a ±2g output range, suiting low-frequency vibration monitoring at low power consumption. Features include a power-down mode reaching 1-µA supply current, and built-in self-test, allowing customers to verify the functioning of the sensor after assembly on the board. The motion sensors also suit devices that need to power on or off by activating a remote control during or after a user touches or moves them, controlling the overall power consumption of the circuitry. The family also aims at medical applications, monitoring motion or detecting the position or activity level of patients. Available in a 5×3×0.9-mm plastic package, the ultracompact design provides shock survivability as high as 10,000g in 0.1 msec. The LIS302ALK costs $2.95 (30,000).
