EVALUATION BOARD CIRCUITRY

This section describes the key parts on the development board.

GYROSCOPE

The ADXRS290
in-plane) angular rate sensor (gyroscope) designed for use in
stabilization applications. The
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
0.004° /s/Hz and features programmable high-pass and low-
pass filters.

MICROCONTROLLER

The microcontroller on EVAL-ADXRS290Z-MLP is
ADUC7026. It is fully integrated, 1MSPS, 12-bit data
acquisition systems incorporating high performance twelve
channel ADCs, 32-bit MCU, and Flash/EE memory on a single
chip. There are also four channel 12-bit voltage output DAC on
ADUC7026 which are used to control the power supply of
ADXRS290. The development tools, like ARMWSD serial
downloader, evaluation version IAR, evaluation version Keil
etc., are available online and they can be found from the
