Using the L20G20IS dual-axis micro MEMS gyroscope with smaller size, improved performance and anti-vibration function, ST's smaller and thinner mobile phone camera module can achieve accurate image stabilization and release new functions for smartphones. Multiple board space.
The L20G20IS is ST's latest highly integrated optical image stabilization gyroscope, which is only 2.0mm x 2.0mm x 0.7mm, which is 1.29mm2 smaller than the previous generation 2.3mm x 2.3mm L2G2IS release board space. The size of the camera module simplifies circuit design. The unparalleled 6dB rejection ratio enables excellent optical image correction and completely eliminates the hand shake problem of cell phone photos.
Ultra-thin substrates are usually only 0.2mm or 0.3mm thick, and are used by more and more designers to design ultra-thin phones with flat cameras and body. Even when soldered to the latest ultra-thin base, the L20G20IS maintains extremely high calibration accuracy. To eliminate substrate distortion during cell phone movement, the L20G20IS maintains a zero-rate level (ZRL) within the specified range, ensuring consistent measurement data for the image stabilization algorithm.
The overall noise performance has also been greatly improved, the rate noise density (RND) is 3.8mdps/√Hz, the configurable phase delay is reduced to 1° at 20Hz, and the ZRL is typically ±5dps, which helps to improve the clarity of the phone. degree. The full scale is not overlooked, up to ±200dps, while sensitivity and temperature stability are improved. The internal temperature sensor ensures that the gyroscope has the highest compensation performance of its class, allowing users to take sharp pictures even after prolonged exposure.
In addition, the L20G20IS has been improved in other areas, for example, the startup time is less than 70ms, 3% faster than the previous generation L2G2IS, and the operating current is only 1.4mA, less than half of the previous generation.
The new product is also about machine and sleep mode, allowing the phone software section to save more battery power.
The L20G20IS is compatible with a single and dual camera module in a 12-pin 2mm x 2mm LGA package and is available today.
