InvenSense, Inc. has introduced its fourth generation of digital 2-axis gyroscopes for Optical Image Stabilization (OIS) in smartphones and drones. The line includes the ICG-1020S and ICG-1020P measuring 2.3 x 2.3 x 0.75 mm and the ICG-1021S and ICG-1021P at reportedly an industry-leading 0.5 mm height for a gyroscope. The lower height matches the most popular companion OIS controllers out on the market today, allowing camera module makers to reduce the module thickness facilitating the continued development of the thinnest smartphones and IoT devices.
The ICG-1020P and ICG-1021P families of InvenSense OIS gyroscopes provide wide bandwidth and low rate noise of 3.5 mdps/√Hz. Each of the OIS sensors supports integrated temperature sensors with advanced temperature compensation algorithms that allow low bias drift for long exposure times despite significant heat from the image sensor.
Every sensor supports 1 percent max sensitivity tolerance to cut up to two minutes from OIS module production time without use of shake tables widely used to reduce the large sensitivity error of standard gyroscopes. Both the ICG-1020 and ICG-1021 families further allow efficient manufacturing by supporting ultrasonic wash methods, commonly used post-component mounting to remove solder particles to prevent them from affecting the image sensor and lens assemblies.
