InvenSense Inc. has launched a family of dual-axis gyroscopes, IDG-2020 and IXZ-2020, that address the market needs for optical image stabilization (OIS) in smartphones.Smartphones are rapidly replacing digital still cameras (DSC) as the devices of choice for capturing images; however, their image quality has generally been worse than DSCs due to blurry images, especially those taken in low-light conditions. By incorporating OIS technology, the same method adopted by many digital still camera manufacturers, smartphone image quality can be dramatically enhanced.
One of the major challenges of incorporating OIS technology into smartphones has been the availability of high performance, small size, and low cost MEMS gyroscopes. InvenSense claims it is the first company to deliver both x-y (roll and pitch) and x-z (roll and yaw) dual-axis MEMS gyroscopes in a very small 3x3x0.75 mm form factor. The new gyroscopes also incorporate a range of high performance features, including16-bit Analog to Digital Converters, less than 6mW of power consumption, and 27kHz drive frequency.
The IDG-2020 (x-y axis) and IXZ-2020 (x-z axis) gyroscopes leverage the company’s Nasiri-Fabrication process, which enables
direct integration of MEMS mechanical structures with CMOS electronics at the wafer level, resulting in simple yet high performance solutions. The new gyroscopes offer features specifically tailored to meet OIS requirements, including the ability to have a factory full-scale output of ±32dps for highest sensitivity to detect hand jitter; high-performance 32kHz ADC sampling; a nominal drive frequency of 27kHz, making the gyroscopes immune to interference from audible frequencies such as music or ambient noise; on-chip16-bit ADCs; low phase delay digital filters; and a high-speed 20MHz SPI serial interface.
The IDG-2020 and IXZ-2020 gyroscopes are now available and sampling to select customers. For more information and data sheets contact InvenSense Sales at sales@invensense.com.
