High-res mems accelerometers

LIS3LV02DQ, a threeaxis accelerometer, comes with a SPI/I2C digital interface and features adjustable bandwidth and direction detection that optimizes performance at various frequencies.

This lets designers combine slow and fast-motion measurements (i.e., tilts and vibrations) at low noise levels and minimal power, which is critical in battery-operated portable systems. Three-axis analog sensors come in two acceleration ranges: LIS3L02AL (±2 g) for tilt applications and LIS3L06AL (±2 and ±6 g) for static and dynamic accelerations, such as vibrations and rollover motions. The 5 5 1.5-mm3 plastic LGA (Land Grid Array) sensors have good high-temperature stability, tight offset tolerances, and resist vibrations and shocks to 10,000 g.
