GENERAL DESCRIPTION 

The 

i

MEMS® 

ADXRS290

 inertial sensor evaluation system is an 

easy-to-use evaluation tool targeting bench or desktop 
characterization of Analog Devices, Inc., inertial sensor products. 
The 

EVAL-ADXRS290Z-M

 system contains the inertial sensor 

evaluation board (ISEB) and the 

EVAL-ADXRS290Z-S

 satellite 

board. In addition, a USB A to mini-B cable is included to connect 
the ISEB to a PC, and an 18-inch, 20-pin ribbon cable is included 
to connect the ISEB to the satellite board. The USB connection 
provides both communications and power to the board. The 
ribbon cable allows users to easily manipulate the satellite board 
for testing or to be separately placed into an environmental 
chamber for temperature or humidity testing. 

Separate the boards to mitigate corruption of data due to the 
temperature and humidity effects of other components. 

The ISEB is a universal main board and is used with various 
satellite boards of Analog Devices inertial sensors, including 
accelerometers and 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. Different shunt resistors are 
used to detect power consumption because the power consumption 
of the gyroscope is relatively high compared to that of the acceler-
ometers. The differences between the 

ADXRS290Z-M

 and other  

-M devices, such as 

ADXL345Z-M

 or 

ADXL362Z-M

, are only 

in the circuit used to detect power consumption. 

Full details about the parts are available in the 

ADXRS290

 data 

sheet, which should be consulted when using the
