ADXRS401

±75°/s Single Chip Yaw Rate Gyro with Signal Conditioning ADXRS401 FEATURES Complete rate gyroscope on a single chip Z-axis (yaw-rate) response High vibration rejection over wide frequency 2000 g powered shock survivability Self-test on digital command Temperature sensor output Precision voltage reference output Absolute rate output for precision applications 5 V single-supply operation Ultra small and light (< 0.15 cc, < 0.5 gram) GENERAL DESCRIPTION The ADXRS401 is a functionally complete and low cost angular rate sensor (gyroscope), integrated with all of the required electronics on one chip. It is manufactured using Analog Devices’ surface-micromachining technique, the same high volume BIMOS process used for high reliability automotive airbag accelerometers. It is available in a 7 mm × 7 mm × 3 mm BGA surface-mount package. The output signal, RATEOUT (1B, 2A), is a voltage proportional to angular rate about the axis normal to the top surface of the package (see Figure 2). A single external resistor can be used to lower the scale factor. An external capacitor is used to set the bandwidth. Other external capacitors are required for operation (see Figure 1). A precision reference and a temperature output are also provided for compensation techniques. Two digital self-test inputs electromechanically excite the sensor to test proper operation of both sensors and the signal conditioning circuits.
