Ultralow Noise, Dual-Axis MEMS Gyroscope Data Sheet ADXRS290 FEATURES GENERAL DESCRIPTION MEMS pitch and roll rate gyroscope The ADXRS290 is a high performance MEMS pitch and roll Ultralow noise: 0.004/s/Hz (dual-axis in-plane) angular rate sensor (gyroscope) designed High vibration rejection over a wide frequency range for use in stabilization applications. Power saving standby mode The ADXRS290 provides an output full-scale range of 100/s with 80 A current consumption in standby mode a sensitivity of 200 LSB//s. Its resonating disk sensor structure Fast startup time from standby mode: <100 ms enables angular rate measurement about the axes normal to the Low delay of <0.5 ms for a 30 Hz input at the widest sides of the package around an in-plane axis. Angular rate data bandwidth setting is formatted as 16-bit twos complement and is accessible through Serial peripheral interface (SPI) digital output a SPI digital interface. The ADXRS290 exhibits a low noise floor Programmable high-pass and low-pass filters of 0.004/s/Hz and features programmable high-pass and low- 2000 g powered acceleration survivability pass filters. 2.7 V to 5.0 V operation The ADXRS290 is available in a 4.5 mm 5.8 mm 1.2 mm, 25C to +85C operation 18-terminal cavity laminate package. 4.5 mm 5.8 mm 1.2 mm cavity laminate package APPLICATIONS Optical image stabilization Platform stabilization Wearable products FUNCTIONAL BLOCK DIAGRAM SYNC/ASEL PDMY PDMX AST V CP V V DD I/O REG S POWER GND MANAGEMENT DEMOD PITCH ADC FILTERS CONTROL LOGIC DEMOD ROLL ADC MOSI MISO SERIAL INPUT/OUTPUT SCLK DIGITAL CS ADXRS290 MECHANICAL PITCH SENSOR ROLL PLL DRIVE VELOCITY Figure 1.
