The analog output ADXL356 and the digital output ADXL357 are low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL356B supports the ±10 g and ±20 g ranges, the ADXL356C supports the ±10 g and ±40 g ranges, and the ADXL357 supports the ±10.24 g, ±20.48 g, and ±40.96 g ranges.
The ADXL356/ADXL357 offer industry leading noise, minimal offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration.
Low drift, low noise, and low power ADXL357 enables accurate tilt measurement in an environment with high vibration, such as airborne IMUs. The low noise of the ADXL356 over higher frequencies is ideal for wireless condition monitoring.
The ADXL357 multifunction pin names may be referenced by their relevant function only for either the SPI or I2C interface.Applications
- Inertial measurement units (IMUs)/altitude and heading reference systems (AHRSs)
- Platform stabilization systems
- Structural health monitoring
- Seismic imaging
- Tilt sensing
- Condition monitoring
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
