Gyroscope-on-a-chip is `a first`

The semiconductor manufacturer Analog Devices has developed a "gyroscope-on-a-chip" which, it asserts, is the first commercial device to combine an angular rate sensor and signal processing electronics on a single piece of silicon. It claims that the device, which measures the rate at which objects rotate, is smaller, more accurate, more reliable and more economical than comparable angle rate sensors.

The iMEMS ADXRS gyro is based on MEMS (microelectromechanical systems) technology. The chip is mounted inside a 7mm by 7mm by 3mm package and consumes just 3mA at 5V. It is claimed to be the only commercial gyro with a full mechanical and electrical self-test that can operate when it is active.

The shock-proof sensor, available in two dynamic ranges of 150 or 300 degrees per second, is aimed at vehicle and industrial applications. Initially it will cost $30 in 1,000-off quantities, but Analog expects the price to fall to $10 in volume production.
