A sensor adjusting circuit for adjusting a digital sensor, whose circuit scale is small and which can maintain high accuracy in a wide adjustment range is provided. A sensor adjusting circuit for adjusting an analog input signal inputted from a sensor and outputting it as another analog output signal in accordance with a physical quantity to be sensed, comprises: a first analog-to-digital converter having an analog integrator ( 2 ) for integrating the analog input signal, a comparator ( 3 ) for comparing an output of the analog integrator with a predetermined value, and a D/A converter ( 7 ) for outputting an output of the comparator as the input signal; and a second digital-to-analog converter ( 5 ) for converting the output of the comparator and outputting it as the analog output signal.
