Overview
The AD22293Z-RL, produced by Analog Devices Inc., is a high-precision, low-power, dual-axis accelerometer. This component is part of the ADXL203 series and is integrated into a single, monolithic IC. It measures 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 device features signal-conditioned voltage outputs and is housed in a compact 5 mm × 5 mm × 2 mm, 8-terminal ceramic LCC package.
