ADXRS646:  High Stability, Low Noise Vibration Rejecting Yaw Rate Gyro

Product Details

The ADXRS64x family of low noise, vibration rejecting yaw rate gyroscopes are drop-in performance upgrades to existing designs using the ADXRS62x family.

The ADXRS646 is pin- and package-compatible to the ADXRS62x family and offers a measurement range of ±250°/s, 1 kHz bandwidth, 12°/hr drift with low broadband noise, low g sensitivity of 0.015°/s/g and vibration rectification of 0.0001°/s/g², is ideally suited for high performance navigation and platform stabilization.

The ADXRS646 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc. patented high volume BiMOS surface-micromachining process to make a complete gyro on one chip. An advanced, differential, quad sensor design rejects the influence of linear acceleration and vibration, enabling the ADXRS646 to offer rate sensing in harsh environments where shock and vibration are present.

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 measurement range is a minimum of ±250°/s. The output is ratiometric with respect to a provided reference supply. 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 ADXRS646 is available in a 7 mm × 7 mm × 3 mm BGA chip-scale package.
