摘要: The invention relates to a controller (200) for controlling rotation rate sensor, having first control circuit (202) and second (204). has unit (210) an oscillation of the sensor along direction, digital-to-analog converter (240) converting digital signal (215) output by into analog (245) with which direction is controlled, analog-to-digital (250) measurement (235) describes read-out (255) supplied (210). (204) (220) different from (270) (225) (275) controlled. During conversion process, (240), (270), each operates using reference voltage (241, 251, 271), at least two voltages 271) are dependent on other.
