Digital Dual-Axis Gyroscope Makes Still Pictures Stiller

In the IDG-2000 dual-axis MEMS gyroscope, designers of digital still cameras and high-resolution camera phones will find a smaller and thinner gyroscope suited for improving optical image stabilization (OIS). The IDG-2000 is fabricated on larger 8-in. wafers to meet increased volume capacity and to further reduce the overall cost. Housed in a 4 x 4 x 0.9-mm QFN plastic package, the IDG-2000 is claimed as the first digital dual-axis pitch and roll (X- and Y- axis) gyro with integrated 16-bit analog-to-digital converters that allow for direct communication to advanced image processors over an I²C or SPI serial bus, eliminating costly discrete components. Other key features include automatic gain amplification control, anti-aliasing filters optimized for OIS applications, and cross axis sensitivity of less than ±1%. The IDG-2000 measures hand jitter across a wide frequency range of 0.1 Hz to 20 Hz with exceptionally low noise at 0.033°/s-rms. Furthermore, the operating frequency in the 30 KHz range is immune to ambient noise. Power consumption is reduced by 50% compared to analog gyros with a low 4-mA maximum current at 2.1 V in active mode and 5 µA maximum current in sleep mode. Sampling begins in October 2009.
