Roll over gyroscope

Analog Devices has introduced a MEMs-based gyroscope that is claimed to be the first commercially available device to integrate both an angular rate sensor and signal processing electronics onto a single piece of silicon.

The ADXRS gyro itself is mounted inside a small 7 mm x 7 mm x 3 mm ball grid array (BGA) package, and consumes only 5 mA of current at 5V.

The ADXRS gyro delivers stable output in the presence of mechanical noise up to 2000g over a wide frequency range. This capability is important in applications such as automotive rollover detection, where a rollover event must be accurately detected while the vehicle is experiencing shocks and vibrations induced by collisions with other objects and off-pavement surfaces.

The gyro is offered in two versions to accommodate different customer requirements for dynamic range.

The ADXRS300 provides dynamic range of 300 degrees/second, and the ADXRS150 provides dynamic range of 150 degrees/second.

Both are priced at $30 per unit in 1,000-piece quantities. Samples are currently available and both products will be in full production by the end of 2002.
