Ultralow noise, dual-axis MEMS Gyroscope for Stabilization Applications

The ADXRS290 is a high performance 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.
