1 / 19 page Ultralow Noise, Dual-Axis MEMS Gyroscope Data Sheet ADXRS290 FEATURES MEMS pitch and roll rate gyroscope Ultralow noise: 0.004°/s/√Hz High vibration rejection over a wide frequency range Power saving standby mode 80 µA current consumption in standby mode Fast startup time from standby mode: <100 ms Low delay of <0.5 ms for a 30 Hz input at the widest bandwidth setting Serial peripheral interface (SPI) digital output Programmable high-pass and low-pass filters 2000 g powered acceleration survivability 2.7 V to 5.0 V operation −25°C to +85°C operation 4.5 mm × 5.8 mm × 1.2 mm cavity laminate package APPLICATIONS Optical image stabilization Platform stabilization Wearable products GENERAL DESCRIPTION The ADXRS290 is a high performance MEMS pitch and roll (dual-axis in-plane) angular rate sensor (gyroscope) designed for use in stabilization applications. The ADXRS290 provides an output full-scale range of ±100°/s with a sensitivity of 200 LSB/°/s. Its resonating disk sensor structure enables angular rate measurement about the axes normal to the sides of the package around an in-plane axis. Angular rate data is formatted as 16-bit twos complement and is accessible through a SPI digital interface. The ADXRS290 exhibits a low noise floor of 0.004°/s/√Hz and features programmable high-pass and low- pass filters. The ADXRS290 is available in a 4.5 mm × 5.8 mm × 1.2 mm, 18-terminal cavity laminate package.
