There are provided a touch input sensing device and a method thereof. The touch input sensing device includes a panel integrally provided with a display device and including a plurality of sensing electrodes; a sensing circuit unit generating an analog signal from capacitance variations generated in the plurality of sensing electrodes; a signal converting unit generating a digital signal from the analog signal; and a calculating unit judging a touch input from the digital signal, wherein the signal converting unit generates the digital signal by measuring a time required for the analog signal to reach a predetermined reference signal level and controls a time at which the sensing circuit unit generates the analog signal by judging whether the measured time is included in an activation time period of a clock signal of the display device. |
