TDK Invensense IAM-20685 6-axis MEMS gyroscope and accelerometer

Taking advantage of TDK’s proprietary MEMS fabrication platform and technology, the IAM-20685 features a highly integrated single-chip 6-axis MEMS gyroscope and accelerometer combination in a small plastic package. Offering unparalleled low-power consumption, compared to competitive sensor solutions within the same product category, the IAM-20685 enables system-orientation-free mounting and unprecedented design flexibility for autonomous systems applications.

The IAM-20685 delivers six degrees of freedom, sustaining dynamic, highly accurate data under all conditions directly to the ADAS within the vehicle, to automate and enhance the driver experience when driving or parking. It reports high resolution, stable and reliable 16-bits acceleration and angular velocity along the three orthogonal axes. This enables parking-assistance systems to efficiently determine the vehicle’s motion and vision systems to enable stabilization techniques and improve image quality, and for positioning systems to enhance absolute position accuracy. Due to six separate masses integrated in its monolithic structure, IAM-20685 offers small cross-axis sensitivity and allows for accurate reporting of linear acceleration and angular velocity into the vehicle’s reference frame, regardless of the installation mounting orientation, to improve design flexibility and ADAS performance.
