GENERAL DESCRIPTION
The iMEMS®
ADXL372
inertial sensor evaluation system is an
easy-to-use evaluation tool targeting bench or desktop charac-
terization of Analog Devices, Inc., inertial sensor products. The
system consists of the inertial sensor evaluation board (ISEB),
or motherboard, and a satellite board for any Analog Devices
inertial sensor product. The ISEB connects directly to a PC via a
USB cable. The USB connection provides both communications
and power to the ISEB.
The ISEB connects to the satellite board through a ribbon cable.
The ribbon cable allows the satellite to be easily manipulated for
testing or separately placed into an environmental chamber for
temperature or humidity testing. Separating the boards mitigates
corruption of data caused by the temperature and humidity
effects of other components.
The ISEB is a universal motherboard for use with various satellite
boards for Analog Devices inertial sensors, including analog
and digital accelerometers and gyroscopes. The various products
are evaluated by means of separate graphical user interfaces
(GUIs) that are customized for performance and characterization
measurements relevant to the inertial sensor being evaluated.
There are two types of motherboards, one named –M and the
other named –MLP. The differences between –M and –MLP are
the shunt resistor, R13, and the gain resistor, R17, which detect
the power consumption of the device under test (DUT). The
EVAL-ADXL372Z-M uses the –M motherboard. The EVAL-
ADXL372Z-M is a system solution that includes the motherboard,
satellite board, cables, and software.
Because the
ADXL372
is pin-to-pin compatible with ADXL362,
the
ADXL372
and
ADXL362
The EVAL-ADXL372Z-M system contains the ISEB and the EVAL-
ADXL372Z-S satellite. Also included is a 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 board.
