AccelRate 3D
Triaxial Accelerometer & Gyroscope
Analog Inertial Sensor
Product Specification
Document Number: DSS-0802
Document Revision - M
Functional Description
The AccelRate3D is the world’s smallest commercially available analog inertial measurement unit, providing analog outputs of triaxial acceleration and rate of turn (gyro) data. The AccelRate3D also provides precision references for the X, Y, and Z-axes as well as temperature outputs allowing the implementation of compensation techniques. A digital self-test input electromechanically excites each axis to test proper operation of both sensors and the signal conditioning circuits. The AccelRate3D is available in a custom SMT package measuring 0.70 × 0.70 × 0.40 inches.
