Description: The ITG-3200 is the world’s first single-chip, digital-output, 3-axis MEMS motion processing gyro optimized for gaming, 3D mice, and motion-based remote control applications for Internet connected Digital TVs and Set Top Boxes. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I²C (400kHz) interface. Additional features include an embedded temperature sensor and a 2% accurate internal oscillator. This breakthrough in MEMS motion processing gyro technology provides a dramatic 60% package size reduction, delivers a 60% power reduction, and has inherent cost advantages compared to competing multi-chip gyro solutions.

By leveraging the patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS wafers with companion CMOS electronics through wafer-level bonding, InvenSense has driven the ITG-3200 package size down to a revolutionary footprint of 4x4x0.9mm (QFN), while providing the highest performance, lowest noise, and the lowest cost semiconductor packaging required for handheld consumer electronic devices. The part features a robust 10,000g shock tolerance, as required by portable consumer equipment.

For enhanced power supply flexibility, the ITG-3200 offers a separate VLOGIC reference pin in addition to its analog supply pin, which sets the logic levels of its I²C interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD max.

Features:

  • Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
  • 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
  • Standby current: 5μA
  • Digital-output temperature sensor
  • Fast Mode I2C (400kHz) serial interface
  • Optional external clock inputs of 32.768kHz or 19.2MHz to synchronize with system clock

  • Remove the last line left over from the breakout board description, because those sure aren’t breadboard friendly:) “Pins broken out to a breadboard friendly 7-pin 0.1” pitch header"

  • Has anyone tried to hook this sensor up to a DAQ and analyze the digital signals and convert it back to analog signals?

  • Datasheet link: https://www.sparkfun.com/datasheets/Sensors/Gyro/PS-ITG-3200-01-01.4.pdf Is a broken link

  • @VTGuy:
    Check invensense.com…. I’m sure you will find something that will tell you what you need on there… There’s more than one data sheet on the web site..

  • Does anyone know if it is possible to change the range on these? +/-2000g range probably won’t be accurate enough for my purpose. I do however like having all xyz on one chip. Space on my board is at a premium!

  • The only thing missing from the info-blurb above is the +/- 2000 deg/sec full range resolution. might get one of these soon :)

  • I love Sparkfun and I love this product, but what’s up with the 250% markup? Cdiweb is selling these things for $10, granted they charge another $10 shipping too. I’m just saying that if you guys dropped the price to $15 I would gladly pay a 50% ‘Sparkfun Tax’.

    • Thanks for the link… I just got 2 with shipping for $3 more than here. I totally agree with your idea, though. Add enough to the price that we don’t balk and I’d be happy to pay it.

  • When will these be back in stock?

  • Will these be coming back in stock soon?
