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.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The dimensions of the EVAL-ADXRS290Z are 20 mm × 20 mm with mounting holes set 15 mm × 15 mm at the corners of the printed circuit board (PCB).
See the ADXRS290 data sheet for configuration of the accelerometer after it is connected to the application host processor.
The EVAL-ADXRS290Z has five factory installed capacitors The primary communications port is the 4-wire SPI interface. For this device, external pull-up/pull-down resistors are not required for the SPI interface, and these pins can be connected directly to the system micro controller.
The EVAL-ADXRS290Z is not reverse polarity protected. Reversing the VS or VDD I/O supply and GND pins can cause damage to the ADXRS290.
Dropping the EVAL-ADXRS290Z on a hard surface can generate several thousand g’s of acceleration, which may exceed the data sheet absolute maximum limits. See the ADXRS290 data sheet for more information.
The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated. Since the power consumption of gyro is relatively high compared with the accelerometers, different shunt resistor have to be used to detect its power consumption, the difference between ADXRS290 –M with other –M is just the circuits for detecting the power consumption of the gyroscope.
The EVAL-ADXRS290Z-M system contains the ISEB and the EVAL-ADXRS290Z-S satellite board. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.
