GENERAL DESCRIPTION
The iSensor® family of products provides a serial peripheral inter-
face (SPI) for data communications. The SPI interface and a
well-calibrated cluster of sensors enable quick integration into
systems that employ embedded processor systems. For users who
are familiar with embedded processors, integrating the iSensor
device with a familiar processor system enables development
with familiar software tools, provides more flexibility, and enables
more design reuse after the initial sensor evaluation is complete.
For users who are unfamiliar with embedded processors and
their development tools, the EVAL-ADIS system provides a
simple PC-based tool for getting started with iSensor products.
The EVAL-ADIS circuit board provides tapped holes (M2 ×
0.4 mm), and the kit includes an assortment of M2 × 0.4 mm
machine screws for a simple device under test (DUT) attach-
ment. The location of the mounting holes facilitates easy
electrical connection with the mating connectors (J1 or J4
on the EVAL-ADIS).
The power management system provides jumper selection for
three device under test (DUT) power options: 5 V (USB), 3.3 V,
and an external power option. The 5 V option provides access
to the USB’s 5 V supply voltage for the DUT, and the 3.3 V

option uses a linear regulator, 400 µF of bulk capacitance, and a
soft start circuit to manage transient currents on the USB port.
The evaluation software packages, which support operation
with the EVAL-ADIS, typically offer three modes of operation:
demonstration, register access, and data capture. In most cases, the
demonstration mode will be a simple waveform recorder function,
which provides a simple visual response to sensor motion. The
waveform recorder is useful in concept demonstrations or
functional verification of units. Individual register read and
write cycles are available in the Register Access window. PC
data acquisition is available using the Data Capture window,
which provides various control inputs, including data register
selection, data file format, and data storage location. In data
capture mode, the EVAL-ADIS reads and stores data from each
selected register every time that the sensor’s data-ready signal
pulses. This synchronous capture mode supports the ADIS16488
(10 registers, 16-bits wide, 2.46 kSPS)
The EVAL-ADIS kit includes a USB mini cable for quick
connection to a PC. The IMU evaluation software package
supports operation on Windows® XP, Windows Vista, and
Windows 7 (32-bit and 64-bit) PC systems.
