One- and two-axis gyroscopes
20 January 2010
Analogue, Mixed Signal, LSI
STMicroelectronics has expanded its motion sensor portfolio with a range of 13 new single- and two-axis gyroscopes. The new single-axis (yaw) and two-axis (pitch-and-roll, pitch-and-yaw) MEMS gyroscopes fit in miniature packages of 3 x 5 x 1 mm and 4 x 5 x 1 mm, respectively. They include a power-down mode (when the entire device is switched off) and a sleep mode, in which part of the circuitry is turned off to significantly reduce power consumption while allowing fast turn-on time and smart power cycling. The devices boast excellent stability over time and a wide temperature range (down to 0,02 dps/°C), eliminating the need for additional temperature compensation in the application. Measurement precision is ensured with a negligible level of output noise (down to 0,01 dps/sqrt(Hz), and wide bandwidth up to 560 Hz, ensuring high accuracy and repeatability.
