Three-axis gyroscope promises power, speed and design-in advantages
STMicroelectronics has unveiled a small, low-power chip-scale gyroscope for advanced motion-sensing applications. ST’s L3GD20H gyroscope measures 3 mm x 3 mm and 1 mm high - the smallest available, according to the company. Occupying little over half the volume of its predecessor, yet offering better resolution, higher accuracy, superior stability and faster response time, the new device enables smaller sensing mechanisms in smart consumer electronics, including mobile phones and tablets, game consoles, digital cameras and industrial tools. The small dimensions of this gyroscope also allow experimental projects such as wearable electronics to move closer towards true practicality. ST’s L3GD20H also helps conserve battery power by drawing 25 percent lower current than the previous generation of devices. Additional features include three selectable full-scale ranges (245/500/2000 dps), I2C/SPI two-line digital interface, integrated low- and high-pass filters with user-selectable bandwidth, power-down and sleep modes, embedded temperature sensor and FIFO.
