## Features

1. 3-axis acceleration sensing: Captures X/Y/Z 3D acceleration. Tilt angle can be calculated under static condition, usable as inclinometer.

2. Software-selectable ranges: ±1.5g/3g/6g configurable via registers for different application scenarios.

3. Continuous built-in self-test: Checks the entire signal chain every measurement cycle, outputs diagnostic flags upon faults including reference monitoring, communication verification and out-of-range detection.

4. Mechanically damped anti-vibration design: Suppresses external vibration interference and maintains high accuracy under harsh vibrating environments.

5. High-speed SPI digital output, directly interfaced with MCU, no external ADC required.

6. Low-power mode, suitable for battery-powered devices.

## Applications

- Industrial Equipment: High-precision level meters, inclinometers, platform leveling, construction machinery, surveying instruments, Structural Health Monitoring (SHM), IMU for AGVs

- Automotive: ADAS, vehicle attitude monitoring, smart transmission control (AEC-Q100 automotive grade)

- Motion Control: Robot attitude, motion analysis, navigation systems

- Others: High-end weighing equipment, medical device attitude monitoring

> Core Advantages: Stable performance across wide temperature range, low bias drift and strong vibration resistance. Ordinary MEMS accelerometers tend to suffer accuracy drift under vibration. The SCA3300-D01 is engineered to solve this pain point, ideal for demanding scenarios requiring high precision in tilt and attitude measurement.
