ITG-3400

[InvenSense, Inc.]

Product Overview

The ITG-3200 is the world’s first single-chip, digital-output, 3-axis MEMS gyro IC optimized for gaming, 3D mice, and 3D remote control applications. The part features enhanced bias and sensitivity temperature stability, reducing the need for user calibration. Low frequency noise is lower than previous generation devices, simplifying application development and making for more-responsive remote controls.

Applications

● Motion-enabled game controllers
● Motion-based portable gaming
● Motion-based 3D mice and 3D remote controls
● “No Touch” UI
● Health and sports monitoring

Features

The ITG-3200 triple-axis MEMS gyroscope includes a wide range of features:
● Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros)
on one integrated circuit with a sensitivity of
14.375 LSBs per °/sec and a full-scale range of ±2000°/sec
● Three integrated 16-bit ADCs provide simultaneous sampling
of gyros while requiring no external multiplexer
● Enhanced bias and sensitivity temperature stability reduces
the need for user calibration
● Low frequency noise lower than previous generation devices,
simplifying application development and making
for more-responsive motion processing
● Digitally-programmable low-pass filter
