Overview
The AD22293Z-RL7, produced by Analog Devices Inc., is part of the ADXL203 series of high-precision, low-power, dual-axis accelerometers. These devices utilize a polysilicon surface micromachined sensor integrated into a single, monolithic IC. They are designed to measure acceleration with full-scale ranges of ±1.7 g, ±5 g, or ±18 g, making them suitable for both dynamic and static acceleration measurements, such as vibration and gravity.
The ADXL203 series is known for its high accuracy, low noise floor of 110 μg/√Hz, and ratiometric sensitivity, which allows for precise tilt sensing and vibration monitoring. The devices operate on a single supply voltage ranging from 3 V to 6 V and are RoHS compliant, compatible with both Sn/Pb and Pb-free solder processes.
