    • A touch sensing apparatus includes a touch screen panel including first electrodes along a first direction and second electrodes along a second direction crossing the first direction to form capacitances with the first electrodes, a driving circuit configured to supply a driving signal to the first electrodes; and a sensing circuit configured to detect output sensing signals from the second electrodes and recognize a touch input based on the output sensing signals. The sensing circuit includes a switching unit configured to modulate the output sensing signals by providing codes as respective input sensing signals to the second electrodes, an amplifying unit configured to amplify the modulated sensing signals, an analog-digital conversion unit configured to convert the amplified sensing signals into digital sensing signals, and a controller configured to demodulate the digital sensing signals and detect a touch input and its position from the demodulated sensing signals.
