New family of MEMS gyroscopes

2 September 2009 Analogue, Mixed Signal, LSI

STMicroelectronics has introduced a new family of single- and multi-axis MEMS (micro electromechanical systems) gyroscopes for angular-motion detection in human-machine interface applications, personal and car navigation systems, and image stabilisation for digital still and video cameras.

The new devices boast excellent stability over a wide temperature range and time, with variation typically lower than 0,05 dps/°C for zero-rate level, eliminating the need for further temperature compensation in the application. Measurement precision is ensured with the negligible level of noise that affects the output signal – 0,014 dps/sqrt(Hz) at 30 dps full-scale.

Housed in a 5 x 5 mm LGA package, the gyroscopes are resistant to mechanical stress and are able to operate with any supply voltage in the range of 2,7 to 3,6 V. Devices are available with full scales ranging from 30 dps to 6000 dps. Examples include the LPR503AL, a two-axis pitch-and-roll gyroscope with 30 dps and 120 dps full scales, and the LPY550AL, a two-axis pitch-and-yaw gyroscope with 500 dps and 2 000 dps full scales.
