Dual-Axis MEMS Gyro Evaluation Board
IXZ-650EVB
FEATURES
GENERAL DESCRIPTION
The IXZ-650EVB provides a simple means of evaluating the IXZ650 X- and Z-axis angular rate gyroscope. The gyro contains all
required conditioning electronics in a single chip measuring 4 x 5
x 1.2mm. The IXZ-650 incorporates X- and Z-axis low-pass filters
and an EEPROM for on-chip factory calibration of the sensor.
Factory trimmed gyro scale factors eliminate the need for external
active components and end-user calibration.
A built-in
Proportional-To-Absolute-Temperature (PTAT) sensor provides
temperature compensation information. The product is lead-free
and Green Compliant.

IXZ-650EVB
Special Instructions
Electrostatic Discharge Sensitivity
The IXZ-650 gyro can be permanently damaged by an electrostatic discharge. ESD precautions for
handling and storage are recommended.
Jumper Connector
The IXZ-650 evaluation board is equipped with a jumper connector to control the voltage supplied to the
gyro. When the jumper is located in the “up” or standard position as shown in the picture above, the 5
Volts being supplied to the gyro is regulated to 3 Volts using an on-board regulator. When the jumper is
located in the “down” position, the on-board regulator is bypassed and the gyro is being directly supplied
with the voltage on Pins 9 and 19 of the IC.
