STMicroelectronics Expands Angular Motion-Sensor with New Single and Two-Axis Gyroscopes

ST’s new high-performance angular-motion sensors open the way to a wide range of innovative consumer applications, including gesture-controlled gaming and pointing devices, image stabilization in digital video or still cameras, and assisted GPS navigation. ST’s newest single-axis (yaw) and two-axis (pitch-and-roll, pitch-and-yaw) MEMS gyroscopes fit in miniature packages of 3×5x1 and 4×5x1 mm3, respectively, addressing the size constraints of today’s and tomorrow’s consumer applications. Power consumption is another key factor, especially in battery-operated devices. Therefore, ST’s gyroscopes include a power-down mode (when the entire device is switched off) and a sleep mode, in which part of the circuitry is turned off to significantly reduce power consumption while allowing very fast turn-on time and smart power cycling. ST’s new gyroscopes boast excellent stability over time and a wide temperature range (down to 0.02 dps/°C), eliminating the need for additional temperature compensation in the application. Measurement precision is ensured with a negligible level of output noise (down to 0.01 dps/sqrt(Hz), and wide bandwidth up to 560Hz, ensuring high accuracy and repeatability. ST’s MEMS gyroscope family offers the industry’s widest full-scale range, from 30 to 6,000 dps, covering a broad spectrum of applications that require high resolution and stability over time and temperature…
