Overview
The AD22037Z, part of the ADXL203 series, is a high precision, low power, complete dual-axis accelerometer produced by Analog Devices Inc. This device is integrated into a single, monolithic IC and features signal conditioned voltage outputs. It is designed to measure acceleration with full-scale ranges of ±1.7 g, ±5 g, or ±18 g, making it suitable for both dynamic and static acceleration measurements, such as vibration and gravity.
The AD22037Z is housed in an 8-terminal ceramic LCC package, measuring 5 mm × 5 mm × 2 mm, and operates within a temperature range of –40°C to +125°C. It is RoHS-compliant and compatible with both Sn/Pb- and Pb-free solder processes.
