ITG-3205

ITG-3205
Three-Axis MEMS Gyroscope with 16-bit ADCs and Signal Conditioning, QFN24, InvenSense, RoHS

The ITG-3205 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.

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
• Low 6.5mA operating current consumption for long battery life
• Wide VDD supply voltage range of 2.1V to 3.6V
• Flexible VLOGIC reference voltage allows for I2C interface voltages from 1.71V to VDD
• Standby current: 5µA
• 10,000 g shock tolerant
• On-chip timing generator clock frequency is accurate to +/-2% over full temperature range
• Optional external clock inputs of 32.768kHz or 19.2MHz to synchronize with system clock
