GENERAL DESCRIPTION The ADXRS645 is a high performance angular rate sensor with excellent vibration immunity for use in high temperature environments. The ADXRS645 is manufactured using the Analog Devices, Inc., patented high volume Bi MOS surface-micromachining process with years of proven field reliability. An advanced, differential, quad sensor design provides superior acceleration and vibration rejection. The output signal, RATEOUT, is a voltage proportional to the angular rate about the axis normal to the package lid. The measurement range is a minimum of ±2000°/sec, and may be extended to ±5000°/sec with the addition of a single external resistor. The output is ratiometric with respect to a provided reference supply. Other external capacitors are required for operation. A temperature output is provided for pensation techniques. Two digital self-test inputs electromechanically excite the sensor to test proper operation of both the sensor and the signal conditioning circuits. The ADXRS645 is available in an 8 mm × 9 mm × 3 mm, 15-lead brazed lead tri in-line package. Rev.
