Triple-Axis Digital-Output Gyroscope - ITG-3200

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.

  • 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

Triple-Axis Digital-Output Gyroscope - ITG-3200 Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    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"

  • GraysonR / about 10 years ago / 1

    So can this be used as a level to measure an objects orientation when not necessarily in motion, so as to enable a microcontroller to send corrections a stabilizing apparatus?

  • Member #481824 / about 10 years ago / 1

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

  • Technical Vault / about 11 years ago / 1

    Datasheet link: Is a broken link

    • Member #268184 / about 11 years ago / 1

      Correct Link would be:

  • mehmetg / about 13 years ago / 1

    Check 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..

  • VTGuy / about 13 years ago / 1

    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!

  • SlyVixsky / about 13 years ago / 1

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

  • jeffmajeff / about 14 years ago / 1

    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'.

    • hpux735 / about 13 years ago / 1

      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?

  • Rocketmagnet / about 14 years ago / 1

    Will these be coming back in stock soon?
