Abstract: A touch panel driving device, for sequentially performing scanning for selecting a pair of adjacent transmission signal lines and a pair of adjacent reception signal lines on a touch panel, includes a reception circuit configured to receive reception signals whose waveforms are changed by a capacitance change caused by an operation from the pair of reception signal lines of the touch panel and generate a detection value for monitoring a touch panel operation. The reception circuit generates the detection value by comparing levels of the reception signals from the reception signal lines while sequentially switching capacitance values of a measurement capacitance unit connected to one of the reception signal lines. The measurement capacitance unit includes capacitance units each forming a certain capacitance value by parallel connection or series connection of capacitors as a capacitance unit forming one capacitance value used for switching the capacitance value of the measurement capacitance unit.
