Three-axis gyroscope

12 October 2011 Analogue, Mixed Signal, LSI

STMicroelectronics’ new L3GD20 is a three-axis, digital-output gyroscope housed in a 4 x 4 x 1 mm package. With a resonant frequency above the audio bandwidth, the IC is immune to both mechanical vibrations coupled through the printed circuit board and to audio noise, such as from speakers mounted close to the sensor. The device offers a wide set of user programmable full-scale ranges from ±250 dps up to ±2000 dps, with the low full-scale values for high accuracy of slow-motion sensing and the high range to detect and measure very fast gestures and movements. The device provides a 16-bit data output, together with additional embedded digital features such as configurable low- and high-pass filters.
