GENERAL DESCRIPTION
The IDG-650EVB is a fully-tested evaluation board, providing for
quick evaluation of the IDG-650 X- and Y-axis angular rate
gyroscope. The IDG-650 uses InvenSense’s proprietary MEMS
technology with vertically driven vibrating masses to produce a
functionally complete, low-cost motion sensor. All required
conditioning electronics are integrated into a single chip
measuring 4 x 5 x 1.2mm. It incorporates X- and Y-axis low-pass
filters and an EEPROM for on-chip factory calibration of the
sensor. Factory trimmed 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.
APPLICATIONS
•High-Performance Motion Sensing Game Controllers
•Pointing Devices

Special Instructions
Electrostatic Discharge Sensitivity
The IDG-650 gyro can be permanently damaged by an electrostatic discharge. ESD precautions for
handling and storage are recommended.
Jumper Connector
The IDG-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.
