摘要:
The invention relates to a controller (200) for controlling a rotation rate sensor, having a first control circuit (202) and a second control circuit (204). The first control circuit has a first control unit (210) for controlling an oscillation of the rotation rate sensor along a first direction, a first digital-to-analog converter (240) for converting a first digital control signal (215) output by the first control unit (210) into a first analog signal (245) with which the oscillation of the rotation rate sensor along the first direction is controlled, and a first analog-to-digital converter (250) for converting a first analog measurement signal (235) which describes the oscillation of the rotation rate sensor along the first direction into a first digital read-out signal (255) which is supplied to the first control unit (210). The second control circuit (204) has a second control unit (220) for controlling an oscillation of the rotation rate sensor along a second direction which is different from the first direction and a second digital-to-analog converter (270) for converting a second digital control signal (225) output by the second control unit into a second analog signal (275) with which the oscillation of the rotation rate sensor along the second direction is controlled.
