Sensor drives adoption of advanced motion interfaces

Housed in a 4 x 4 x 1mm package, the L3G462A gyroscope has been designed for gesture control and intuitive user interfaces in mobile phones, tablets, game controllers and other consumer devices. According to the motion sensor specialist, the device employs a unique concept of single sensing structure for motion measurement along all three orthogonal axes. This eliminates interference between the axes and 'significantly' increases accuracy. ST says the full scale of ±625dps accurately measures gestures and movements of different types and speeds, while the analogue interface ensures fast response with low latency. The stability over temperature is ±0.04dps/°C and sensitivity is ±0.017%/°C, while the low noise level is 0.017dps/vHz. The 3 axis analogue output gyroscope can operate with any supply voltage in the range of 2.4 to 3.6V and the power down and sleep to wake modes contribute to the reduction in power consumption of the entire system. Volume production is scheduled for the end of Q3 2011.
