SMA380 | Low-latency acceleration sensor for road noise cancellation

Ultra compact

The SMA380 is a single-channel accelerometer with TDM and I²C interfaces, designed for road noise cancellation.

It enhances driving comfort by detecting and processing vibrations from road noise with low latency.

Power and digital communication are managed through the same connection, ensuring efficient integration into noise reduction systems.
