Description

The AD22037 is a single/dual-axis accelerometer that measures acceleration with a full-scale range of ±1.7 g, ±5 g, or ±18 g. It is a high precision, low power, and complete accelerometer with a signal conditioned voltage output. This model can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). This model is designed to deliver high performance in even the most challenging applications and environments and is RoHS compliant. It is also compatible with Sn/Pb- and Pb-free solder processes and qualified for automotive applications.
