Functional Diagram

General Description

The MLX90609 Angular Rate Sensor is a full

gyroscopic system. A single SMD package

contains a high performance silicon micro

machined sensor with signal conditioning

circuitry. It operates from 5V supply and is

designed

for

demanding

automotive

applications.

The MLX90609 delivers two output signals

proportional to the angular rate perpendicular

to the assembly surface. One of the output

signals is in an analog voltage format (the

output is 2.5V at zero angular rate and the full

scale angular rate produces an output of 4.5V

or 0.5V depending on direction of rotation)

and the other one is in digital SPI format.
