IAM-20680HV 6-axis motion tracking device for cost-effective automotive in-cabin applications*

Proven operating temperature range up to +125 °C with specification guaranteed up to +105 °C

Leading low-noise performance and sensitivity tolerance for accurate positioning

Gyroscope offers a ±125 dps full-scale for enhanced navigation precision

June 24, 2025

TDK Corporation (TSE:6762) today announced global distribution availability of the InvenSense SmartAutomotive™ IAM-20680HV, a high-value 6-axis IMU for a variety of in-cabin applications that also require the component to survive in harsh conditions up to +125 °C, with performance guaranteed up to +105 °C. It relies on robust TDK technology and design that are widely adopted in the automotive market, setting a quality benchmark for non-safety applications.

The IAM-20680HV integrates a 3-axis gyroscope and a 3-axis accelerometer within a compact 3 x 3 x 0.75 mm³ (16-pin LGA) package, offering pin-to-pin and register compatibility with all other TDK SmartAutomotive™ MEMS sensors in LGA packages. Featuring a selectable ±125 dps gyroscope full-scale, the IAM-20680HV provides higher resolution for a seamless user navigation experience. Complementing other products in the same SmartAutomotiveTM family, the IAM-20680HV enriches the IMU product portfolio offering the best trade-off to address cost-effective automotive applications.

With industry-leading low-noise performance, sensitivity tolerance, and high reliability, the product empowers engineers to scale a diverse range of automotive applications, including but not limited to telematics, heads-up displays, navigation systems, door control, and crash-recording.*

“In a fast-evolving automotive industry where high performance must meet affordability; innovation, scalability, and efficiency are no longer options,” said Alberto Marinoni, Senior Director Product Marketing Automotive at InvenSense, a TDK Group company. “Our technology empowers Tier 1s and OEMs to develop cutting-edge solutions in a cost-sensitive environment without compromising on quality or performance.”
