What the ADXL356BEZ is and where it fits
The ADXL356BEZ is a triple-axis analog accelerometer from Analog Devices that outputs X, Y, and Z acceleration as analog voltage signals. It offers a selectable full-scale range of ±10g or ±20g, with corresponding sensitivities of 80 mV/g and 40 mV/g. The bandwidth is adjustable from 1 Hz to 1 kHz via external capacitors, letting you trade noise filtering against response time. Operating from 2.25 V to 3.6 V and rated from -40°C to 125°C, it's built for industrial vibration monitoring, structural health sensing, and inertial measurement in harsh environments.
Package and mounting
Housed in a 14-CLCC ceramic package measuring 6x6 mm, this is a surface-mount part with a hermetic seal — good for humidity and corrosive atmospheres.
Package and mounting
The ±10g range gives you 80 mV/g sensitivity — better signal-to-noise for low-amplitude vibration measurements like bearing wear or fan imbalance. Switch to ±20g (40 mV/g) when you're expecting shocks or higher-g events like impact testing or vehicle dynamics. The bandwidth adjustment is done with a capacitor on the output pin: a 1 kHz corner captures fast transients but passes more noise; dropping to 1 Hz cleans up the signal for steady-state tilt or low-frequency structural monitoring. No internal filter — the external cap is your only low-pass, so plan the PCB layout to keep the cap close and the trace short.
Lifecycle and sourcing
The ADXL356BEZ carries an Active product status and is ROHS3 compliant.
