ADXL354/ADXL355 3-Axis Mems Accelerometers

Analog Devices offers ADXL354/ADXL355 low noise, low drift, low power accelerometers for IMU and AHRS applications

Image of Analog Devices' ADXL354/ADXL355 3-Axis Mems AccelerometersAnalog Devices' ADXL354/ADXL355 perform high-resolution vibration measurement with very-low noise to enable the early detection of structural defects via wireless sensor networks. The low power consumption of the ADXL354 and ADXL355 accelerometers lengthen battery life and allow extended product usage by extending the time between battery changes. The low-noise performance of the ADXL354/ADXL355 with low power consumption make it now possible to cost-effectively enable low-level vibration measurement applications such as structural health monitoring (SHM). Additionally, the tilt stability of ADXL354/ADXL355 accelerometers delivers excellent repeatability over temperature and time, which is ideal for orientation and navigation systems in unmanned aerial vehicles using inertial measurement units (IMUs) and inclinometers. By providing repeatable tilt measurement under all conditions, the accelerometers enable minimal tilt error without extensive calibration in harsh environments.

The ADXL354/ADXL355 are a part of a family of low noise density, low 0 g offset drift, low power, 3-axis MEMS accelerometers with selectable measurement ranges. The ADXL354B supports the ±2 g and ±4 g ranges, the ADXL354C supports the ±2 g and ±8 g ranges. The ADXL354/ADXL355 offers industry leading noise, offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration and with very low power consumption.
