The ADXL202AE is a precision, low-power two-axis accelerometer with signal conditioned voltage outputs, all on a single monolithic IC. Manufactured by the renowned Analog Devices Inc., this accelerometer is designed for applications requiring a high-performance, low-cost acceleration measurement of ±2 g with a bandwidth of 0 to 62.5 Hz.

Key Features

• Dual Axis Sensing: The ADXL202AE can measure both X and Y axes simultaneously, providing a comprehensive solution for tracking dynamic movement.
• Low Power Consumption: It operates on a supply voltage range of 3.0V to 5.25V, drawing a minimal supply current, making it ideal for battery-powered applications.
• Adjustable Bandwidth: Users can set the bandwidth of the ADXL202AE by selecting the appropriate external capacitor, allowing for customization based on the specific needs of the application.
• Duty Cycle Output: The output of the ADXL202AE is a duty cycle (ratio of pulse width to period) proportional to acceleration. The duty cycle output can be easily converted to an analog voltage with a simple RC filter or directly interfaced to a digital system.
• Self-Test Feature: A self-test capability ensures that the sensor is functioning correctly, which is critical for safety-critical applications.
