Claim 0:
1. A sensor processing circuit comprising:
a sensor;
an input part that receives an analog signal output from a signal output part of the sensor;
an analog-to-digital conversion part that digitally converts the analog signal to generate first digital data and second digital data;
a first output part that outputs the first digital data to a control circuit; and
a second output part that outputs the second digital data to the signal output part before the first output part outputs the first digital data, wherein:
the second digital data has a smaller bit number than the first digital data,
the analog-to-digital conversion part includes a first analog-to-digital converter and a second analog-to-digital converter connected in series,
the second analog-to-digital converter is provided at a preceding stage of the first analog-to-digital converter and generates the second digital data,
the second output part outputs the second digital data generated by the second analog-to-digital converter to a sensor as the signal output part,
the sensor receives the second digital data, and
the sensor is an acceleration sensor, a gyro sensor or a motion sensor.
