Product Summary

The AD22282-A-R2 is a low power, complete single-axis accelerometer with signal conditioned voltage outputs that are all on a single monolithic IC. This product measures acceleration with a full-scale range of ±120 g or ±250 g (minimum). It can also measure both dynamic acceleration (vibration) and static acceleration (gravity). The AD22282-A-R2 is a fourth-generation surface micromachined iMEMS accelerometer from ADI with enhanced performance and lower cost. The applications of the AD22282-A-R2 include Vibration monitoring and control, Vehicle collision sensing, Shock detection.
