Overview
FEATURES Complete rate gyroscope on a single chip Z-axis (yaw rate) response High vibration rejection over wide frequency 2000 g powered shock survivability Ratiometric to referenced supply 5 V single-supply operation 105°C operation Self-test on digital command Ultrasmall and light (< 0.
15 cc, < 0.
5 gram) Temperature sensor output RoHS compliant APPLICATIONS Vehicle chassis rollover sensing Inertial measurement units Platform stabilization ±300°/sec Yaw Rate Gyro ADXRS610 GENERAL DESCRIPTION The ADXRS610 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc.
surface-micromachining process to create a functionally complete and low cost angular rate sensor integrated with all required electronics on one chip.
The manufacturing technique for this device is the same high volume BiMOS process used for high reliability automotive airbag accelerometers.
The output signal, RATEOUT (1B, 2A), is a voltage proportional to angular rate about the axis normal to the top surface of the package.
The output is ratiometric with respect to a provided reference supply.
A single external resistor can be used to lower the scale factor.
An external capacitor sets the bandwidth.
Other external capacitors are required for operation.
A temperature output is provided for compensation techniques.
Two digital self-test inputs electromechanically excite the sensor to test proper operation of both the sensor and the signal conditioning circuits.
The ADXRS610 is available in a 7 mm × 7 mm × 3 mm BGA ceramic package.
