±250°/sec Yaw Rate Gyro ADXRS612 FEATURES GENERAL DESCRIPTION Complete rate gyroscope on a single chip The ADXRS612 is a complete angular rate sensor (gyroscope) Z-axis (yaw rate) response that uses the Analog Devices, Inc. surface-micromachining High vibration rejection over wide frequency process to make a functionally complete and low cost angular 2000 g powered shock survivability rate sensor integrated with all of the required electronics on one Ratiometric to referenced supply chip. The manufacturing technique for this device is the same 5 V single-supply operation high volume BIMOS process used for high reliability automotive 105°C operation airbag accelerometers. Self-test on digital command Ultrasmall and light (0.15 cc, 0.5 gram) The output signal, RATEOUT (1B, 2A), is a voltage propor- Temperature sensor output tional to angular rate about the axis normal to the top surface RoHS compliant of the package. The output is ratiometric with respect to a provided reference supply. A single external resistor can be used to lower APPLICATIONS the scale factor. An external capacitor is used to set the bandwidth. Vehicle chassis rollover sensing Other external capacitors are required for operation. Inertial measurement units
