Accelerometers

ST offers a portfolio of MEMS-based linear accelerometers able to sense acceleration or vibration in one, two and even three axes.

The MEMS sensor of a linear accelerometer is based on a silicon, inter-digitated, comb-like structure composed of fixed and movable fingers. To sense the acceleration in different directions, these structures are packaged in orthogonal groups. The acceleration in each direction is sensed by measuring the displacements of the movable elements correlated to that axis. The motion measured by the sensor is then translated into an analog or digital signal.

STMicroelectronics controls the complete manufacturing chain of linear accelerometers. This guarantees the customer high-volume production, long-term security, high precision and reliability, since all the devices are tested by standard and proprietary test systems.

ST low-g linear accelerometers are grouped in subfamilies according to the number of axes (2-axis and 3-axis), the package type (SO24, QFN or LGA) and the IC output (analog or digital).

The key features of ST MEMS-based linear accelerometers are:

high shock survivability
low power consumption in normal mode
power down mode
acceleration noise density <50ug/Hz
embedded self test
operating temperature range: -40/+85°C
