... 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. The ADXRS300 is available × × BGA chip-scale package.

... ADXRS300 THEORY OF OPERATION The ADXRS300 operates on the principle of a resonator gyro. Two polysilicon sensing structures each contain a dither frame, which is electrostatically driven to resonance. This produces the necessary velocity element to produce a Coriolis force during angular rate. At two of the outer extremes of each frame, ...

... Rather they are nominally constant for dc supply changes within the 4. 5.25 V operating range. If the ADXRS300 is used with a supply-ratiometric ADC, the ADXRS300’s 2.5 V output can be converted and used to make corrections in software for the supply variations. NULL ADJUST Null adjustment is possible by injecting a suitable current to SUMJ (1C, 2C) ...
