MEMS motion sensor suits mobile phones

摘要

The LIS352AX MEMS sensor operates with any supply voltage over a 2.16 to 3.6V range and remains stable over time and temperature. The sensor uses a three-axis accelerometer that provides acceleration values in absolute analog outputs. It uses an internally regulated voltage, making the measurements insensitive to typical variations in power-supply voltage in battery-operated devices. The sensor has a direct connection to the battery without the need for a separate voltage regulator, making the device suitable for space- and cost-constrained battery-operated devices. The device has high stability over a wide temperature range for zero-gravity offset and sensitivity and provides a ±0.3-mg°/C offset-drift temperature variation. Available in a 3x5xl-mm~3 plastic package, the LIS352AX MEMS sensor costs $1.30 (10,000)/year.
