STMicroelectronics (ST) Advanced Image Stabilizer Gyroscopes Let Your Next-Generation Smartphone Take Pictures without Jitter

Using STMicroelectronics L20G20IS dual-axis miniature MEMS [1] gyroscope with smaller size, higher performance and improved anti-vibration function, a smaller and thinner camera module for mobile phones can achieve accurate image stabilization and new smartphone applications Function frees up more board space.

The L20G20IS is STMicroelectronics' newest highly integrated optical image stabilization gyroscope with a 2.0mm x 2.0mm x 0.7mm footprint that is 1.29mm2 smaller than the previous generation 2.3mm x 2.3mm L2G2IS release board, which helps reduce the size of your phone Camera module size, simplifying circuit design. Unparalleled 6dB rejection ratio can achieve excellent optical image correction function, the complete eradication of mobile phone camera shake problems.

Slim substrate is usually only 0.2mm or 0.3mm thick, more and more designers are used to design the camera and the body of the thin cell phone. The L20G20IS maintains extremely high calibration accuracy even when soldered to the latest ultra-thin base. In order to eliminate substrate deformation when the phone is moving, the L20G20IS keeps the zero-rate level (ZRL) within the specified range, ensuring consistent measurement data for image stabilization algorithms.

The overall noise performance has also been significantly improved, with a rate noise density (RND) of 3.8mdps / √Hz, a configurable delay of 1 ° down to 20Hz and a typical ZRL of ± 5dps, all of which help improve the clarity of the phone's photography degree. Full scale is not overlooked, up to ± 200dps, both sensitivity and temperature stability are improved. The internal temperature sensor ensures that the gyroscope has the highest level of compensation available in its class, allowing the user to take a sharp picture even with prolonged exposure.

In addition, the L20G20IS has also been improved in other areas, for example, less than 70ms start-up time, 3% faster than the previous generation L2G2IS, operating current of only 1.4mA, less than half of the previous generation.

New products are also related to machine and sleep mode, so that mobile phone software section can save more battery power.

L20G20IS compatible single and dual camera module, package 12-pin 2mm x 2mm LGA, available immediately.
