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.
