Senodia Accelerometers

Choose SCA3300 for consumer, industrial, and general-purpose applications where cost and power consumption are important. Select SCA6300 for automotive applications requiring AEC-Q100 qualification, extended temperature range, and safety-critical operation. The SCA6300 includes additional diagnostic features required for automotive safety systems.

SCA3300 for consumer/industrial; SCA6300 for automotive and safety-critical applications.

Senodia accelerometers offer excellent noise performance ranging from 150μg/√Hz to 200μg/√Hz depending on the model. This low noise enables detection of subtle vibrations and precise tilt measurement. The noise can be reduced further using digital filtering at the expense of bandwidth.

Select model based on noise requirements; use digital filters to reduce noise if lower bandwidth is acceptable.

Senodia accelerometers support standard digital interfaces including I2C (up to 400kHz) and SPI (up to 10MHz). I2C is suitable for simple multi-sensor designs, while SPI provides higher data rates for fast sampling applications. The automotive-grade SCA6300 uses SPI with CRC protection for enhanced reliability.

Use I2C for simple designs; SPI for high-speed or automotive applications.

Yes, Senodia accelerometers are well-suited for vibration monitoring applications. The low noise, wide bandwidth (up to 1kHz), and high resolution enable detection of subtle vibrations. The programmable digital filters allow optimization for specific frequency ranges of interest.

Select appropriate bandwidth and filter settings for your vibration monitoring application.

Senodia accelerometers are available in compact LGA packages (3mm x 3mm) for consumer applications and robust SOIC packages for automotive use. The small LGA package enables integration in space-constrained devices like smartphones and wearables.

LGA for compact designs; SOIC for automotive and high-reliability applications.
