InvenSense unveils gyroscope for high speed motion and wearable applications

InvenSense, Inc., the provider of MotionTracking system on chip (SoC) and sound devices, announced the world’s widest full scale range (FSR) 3-axis MEMS gyroscope for high impact wearable applications. The ITG-3701 also offers the smallest size, lowest profile and lowest power, ideal for wearable applications in sports and concussion analysis. Today’s wearable sports applications require higher than the common ±2000 dps (degrees per second) FSR so that critical data is not lost at the point of impact. The ±4000 dps range of the ITG-3701 enables precise analysis of a golf or tennis racquet swing, soccer ball and basketball applications providing continuous data before, during and after impact. The InvenSense ITG-3701 directly addresses the wearable sports market technology requirements with lowest power consumption of only 5.9mW (3.3mA at 1.8V), extending battery life and an industry first 0.75mm height.

“High-impact sports solutions saturate the gyroscope during the point of contact or very high rotation rate. The ITG-3701 solution with its unrivaled FSR will enable OEMs to collect data during the most critical juncture of a golf or tennis swing,” said Ali Foughi, Vice President of Marketing and Business Development at InvenSense. “The application goes beyond wearable sports as our solution can benefit any application that has high maneuverability and requires high speed motion analysis.”

The InvenSense ITG-3701 flexible programmable ranges of ±500 dps, ±1,000 dps, ±2,000 dps and ±4,000 dps, allows the OEM to pick the best motion range for any activity or context. The solution includes integrated self-test and offset temperature compensation, delivering ease of integration and consistent performance. Other industry-leading features include a 3x3x0.75mm plastic 16-pin QFN package, on-chip16-bit ADCs, outstanding rate noise performance of only 0.02 dps/√Hz, built-in FIFO, programmable digital filters, and programmable interrupts. These SoCs are available with I2C and high-speed SPI serial interfaces, along with a flexible operating range of 1.71V to 3.6V.
