Abstract: A multitouch touch device (DIS) employing capacitive detection, including: a touch matrix array and a first voltage-generating source configured to generate, for each row and each column of the matrix array, a first input voltage having a first frequency leading to the generation of a first output voltage. The device also includes a second voltage-generating source for generating, for each intersection between at least two rows and two columns of the matrix array, a second input voltage having a second frequency different from the first frequency leading to the generation of a second output voltage. A processing circuit is configured to determine, depending on first and second reference values, whether the first and second output voltages are representative of a press and of its position.
