Tronics Microsystems GYPRO series MEMS gyros

Tronics Microsystems, a division of TDK Corporation, has released the GYPRO range of closed-loop MEMS gyros, taking MEMS inertial sensors to a high level of performance with good measuring accuracy and long-term stability.

The MEMS inertial sensors are suitable for system manufacturers with strong requirements for high bias stability and high-performance inertial sensors. Key applications include precision navigation, motion tracking and control, and optical stabilisation. Tronics’ comprehensive sensor portfolio brings a tailored solution to support system manufacturers’ transition to MEMS products, with benefits in terms of size, weight and power without compromising on performance.

The GYPRO series combines several key benefits on a single chip. It features low bias instability of 0.8°per hour and ultralow noise (angular random walk) of 0.14° per √h. The standard GYPRO2300 product features a data rate of 200 Hz with RMS noise (1–100 Hz) of 0.02°/s; the GYPRO2300LD offers a data rate of 1700 Hz at 2 ms latency tailored for motion tracking and stabilisation. The GYPRO3300 features high tolerance to harsh environments (vibration rectification coefficient of 0.5°/h/g²) and a latency of 1 ms due to improved integrated circuitry, tailored for precision navigation and stabilisation.

The built-in closed-loop electronics bring several key advantages, including good linearity, high signal-to-noise ratio and continuous operation in harsh vibration, shock and temperature environments. The products are calibrated over a broad temperature range, allowing for high-accuracy digital output.
