AD22303 – A Motion Sensor – Accelerometer

Motion sensors are devices that measure acceleration, velocity and force. Accelerometers are one of the most popular types of motion sensors and are used in a vast range of applications and industries. The AD22303 is an excellent example as it is designed for high-accuracy measurement of linear acceleration.

Overview

The AD22303 is a full-featured motion sensor from Analog Devices, designed to measure linear acceleration up to a range of ±12 g. It is a piezoresistive accelerometer, which means that the entire sensing element is composed of a single monolithic structure. This design offers excellent performance and accuracy, making it suitable for a variety of applications.

Applications

The AD22303 is a popular choice for a range of different applications due to its accuracy and scalability. It is ideal for automotive and aerospace applications, where precise measurements of linear acceleration are required. Industrial applications such as vibration monitoring and shock testing also make use of this motion sensor.

Working Principle

The AD22303 uses a piezoresistive sensing element to measure linear acceleration. This element is composed of a single monolithic structure, which is composed of multiple layers. On the top layer, two piezoresistor elements are bonded to a silicon diaphragm. As the diaphragm is deflected, the resistance of the piezoresistors changes, creating an electrical signal that is used to measure linear acceleration.

Features

The AD22303 has a range of features that make it a versatile motion sensor. It includes a self-calibration feature which allows it to automatically adjust for environmental disturbances. It also has a wide temperature range, from -40°C to 125°C, making it suitable for use in extreme conditions. Finally, it has two output modes which allow for both digital and analog output.

Conclusion

The AD22303 is an excellent example of a motion sensor – accelerometer, designed for high-accuracy measurement of linear acceleration. It has a range of features, making it suitable for a wide range of applications. Due to its accuracy, scalability and wide temperature range, the AD22303 is an ideal choice for automotive, aerospace and other industrial applications.
