High performance Digital SMD MEMS Gyros

Product Description

GYPRO is a unique family of high performance digital closed-loop MEMS angular rate sensors housed in SMT packages. The force-rebalance architecture of GYPRO makes them extremely linear and insensitive to vibrations and linear accelerations. GYPRO® offers high bias stability and scale factor repeatability, low angular random walk and low latency. Our closed-loop gyroscopes product family is well suited to precision attitude and motion control, stabilization and pointing as well as GNSS-aided positioning and navigation applications.

With its small hermetic SMT package GYPRO® offers a digital and SMD alternative to expensive FOG (Fiber Optic Gyros), DTG (Dynamically Tuned Gyros) or quartz gyros. Its 24 bit SPI interface and factory calibration ease their integration and reduce the bill of material at the system level compared to analog sensors by avoiding expensive low noise ADC and complex temperature modeling and compensation.
