Datasheet ADXRS290 (Analog Devices)

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 ful -scale range of ±100°/s with
80 µA 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 −25°C to +85°C operation
The ADXRS290 is available in a 4.5 mm × 5.8 mm × 1.2 mm,
4.5 mm × 5.8 mm × 1.2 mm cavity laminate package
18-terminal cavity laminate package.
