The present invention relates to a touch screen device and a driving method thereof. A touch screen apparatus according to an embodiment of the present invention, the touch screen panel comprising a touch sensor formed at the intersection of the line with the Tx Rx lines, lines Rx, Tx, and the line; A Tx driving circuit for supplying driving pulses to the Tx line; And the noise of the signal received through the Rx driving circuit, and including a Rx drive circuit for sampling the charge amount of change of said touch sensors received through the Rx line converted to digital data in the touch-low data from the Rx line noise reduction filter; An integrator for accumulating a charge amount of change has passed through the noise filter; A sampling circuit for sampling the accumulated charge amount of change in the integrator; And an analog-to-digital converter which converts the charge amount of change sampling by the sampling circuit to the touch raw data, the noise filter, characterized in that the biquad bandpass filter including a variable resistor and a variable capacitor.
