TOUCH DETECTING DEVICE AND SEMICONDUCTOR DEVICE

The invention relates to a touch detecting device and a semiconductor device, having a second parameter data for correction of a first parameter data. Thus it is easy to perform offset adjustment of a calibration circuit in high precision without stopping detection in the halfway. A touch panel controller is provided with the calibration circuit that performs offset adjustment with respect to input signals of a plurality of detection circuits corresponding to a plurality of X electrodes of the touch panel, and a storage device that stores first parameter data that specifies an offset adjustment operation of the calibration circuit, and second parameter data for correction for the first parameter data.
