MAX21100

Low-Power, Ultra-Accurate 6+3 DoF IMU

The Industry's Smallest and Thinnest 6DoF IMU with Stable and Accurate Gyroscope and Reliable Accelerometer


Please check latest availability status for a specific part variant.

Description

The MAX21100 is a monolithic 3-axis gyroscope plus 3-axis accelerometer Inertial Measurement Unit (IMU) with integrated 9-axis sensor fusion using proprietary Motion Merging Engine (MME) for handset and tablet applications, game controllers, motion remote controls, and other consumer devices.

The MAX21100 is the industry’s most accurate 6+3 DoF inertial measurement unit available in a 3mm x 3mm x 0.83mm package and capable of working with a supply voltage as low as 1.71V.

The MAX21100 can interface an external magnetometer through a dedicated I²C master.

The internal Motion Merging Engine (MME) can be flexibly configured to get the most suitable accuracy power trade-off.

The MAX21100 is available in a 16-lead plastic land grid array (LGA) package and can operate within a temperature range of -40°C to +85°C.
