The ADXL354 is part of a new 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 offers industry leading noise, offset drift over temperature, and long term stability, enabling precision applications with minimal calibration and with very low power consumption.
The ADXL354 and ADXL355 (digital output. See ADXL355 Product Page) 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 new ADXL354 and ADXL355 accelerometers lengthens battery life and allows extended product usage by reducing the time between battery changes. The low noise performance of the ADXL354 and ADXL355 with low power consumption makes it now possible to cost-effectively enable low level vibration measurement applications such as Structural Health Monitoring (SHM). Additionally, the tilt stability of ADXL354 and 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 new accelerometers enable minimal tilt error without extensive calibration in harsh environments.
The ADXL354 and ADXL355 accelerometers offer guaranteed temperature stability with null offset coefficients of 0.15mg/C (max). The stability minimizes resource and expense associated with calibration and testing effort, helping to achieve higher throughput for device OEMs. In addition, the hermetic package helps ensure that the end product conforms to its repeatability and stability specifications long after they leave the factory.
With output of ±2g to ±8g full scale range (FSR), selectable digital filtering from 1 Hz to 1 kHz, and low noise density of 25µ/Hz and150µA current consumption, the ADXL354 MEMS accelerometer offers performance level comparable to much more expensive devices with less power consumption and BOM cost.

Markets & Technology
Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-ADXL35x-Z are simple evaluation boards that allow quick evaluation of the performance of Analog Devices new series of low power, low noise, low drift 3-axis, MEMS accelerometers. The series consists of both analog and digital output devices, supporting a variety of Full Scale Ranges (FSR). The model descriptions are shown in the ordering guide below. These evaluation boards are ideal for evaluation of the ADXL35x accelerometer series in an existing system because the stiffness and the small size of the evaluation board minimize the effect of the board on both the system and acceleration measurements.
Features & Benefits
- 2 sets of spaced vias for populating 6-pin headers
- Easily attachable to prototyping board or PCB
- Small size and board stiffness minimize impact on the system being monitored and acceleration measurements
