GYPRO®4300
High stability ± 300 °/s MEMS gyroscope with digital interface
Precise navigation and positioning for dynamic applications
GYPRO®4300 is a high-performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range that offers a cost-effective alternative to entry-level Fiber-Optic Gyroscopes (FOG) at a fraction of their size, weight, and power consumption.
With an excellent bias instability of 0.5 °/h as typical value (2 °/h maximum) and an ARW (Angular Random Walk) of 0.1 °/√h, GYPRO4300 offers a miniature, digital and low-SWaP (Size, Weight and Power) high performance MEMS gyro that paves the way to a new generation of precise positioning, navigation, and stabilization functions in dynamic applications.
The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of GYPRO®4300 and reduces the BOM. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.
