High-end inertial sensors market: Analog Devices is staying strong with its industrial MEMS IMUs
“For the development of robotics, smart agriculture, autonomous vehicles and navigation and stabilization applications, accurate motion capture sensors have played a central role.” asserts Audrey Lahrach, Technology & Cost Analyst, MEMS, Sensors & Display at Yole SystemPlus, part of Yole Group. She adds:“The requirements in high precision, long mission life and high reliability are not provided by standard consumer solutions”.
Yole SystemPlus disassembles a device or a system to identify its technology and determine its manufacturing processes, and then uses in-house models and tools to calculate its cost. Analog Devices’ IMU components are amongst those components analyzed by Yole SystemPlus. Analog Devices Inc is one of the leaders in the inertial industry, with a 2020 revenue of US$5.6 billion.

In the global high-end inertial sensor market, Analog Devices has a 3% market share and leads the industrial applications, competing with Sensonor, Colibrys/Safran, Silicon Sensing Systems and other silicon MEMS companies. Indeed, according to Yole SystemPlus’s partner, Yole Intelligence, part of Yole Group, in the High-End Inertial Sensors for Defense, Aerospace and Industrial Applications 2020 report: it is important for the companies involved in the high-end inertial market to invest in the right technologies and partners, depending on the end applications targeted. The market is still dominated by Honeywell, Northrop Grumman and Safran, thanks to their large portfolios. All technologies have a long lifetime, due to the specifications of the market, and no abrupt shift from one technology to the others is expected, required that these players keep their technology up to date. This means no outrageous shifts in geographical leadership are expected.
In this dynamic context, Yole SystemPlus, part of Yole Group of Companies, investigates the various MEMS IMU technologies and related markets in depth. The reverse engineering and costing company points out the latest technical choices made by the leading IMU company Analog Devices.
Released today, the Analog Devices High-End Accelerometers and Gyroscopes Comparison report, from Yole SystemPlus analyses the differences in manufacturing process and integration of these devices in different IMUs from ADI with different levels of precision. It also presents a detailed comparative physical analysis with process descriptions and a comparative manufacturing cost analysis between the three accelerometers and the three gyroscopes. A teardown, a bill of material, cost and selling price estimation of each IMU selected is also available.
Most of accelerometers and all gyroscopes contain one main MEMS device and the corresponding ASIC in the same package. All the MEMS devices are manufactured with surface micromachining techniques. The cap and the MEMS sensor are assembled with eutectic bonding or glass frit bonding. Accelerometers are assembled with ceramic packaging, or a LGA package and all gyroscopes are assembled in a LGA package.
According to Audrey Lahrach: “The same accelerometers and gyroscopes are integrated in different IMUs. For different applications we can find combinations of the same accelerometer and gyroscope. Then every IMU is calibrated for different application grades like robotics, internet of moving things, autonomous machines, avionics, precision instrumentation, guidance and navigation”…
