For example, magnetic, cross and to a difference mode of the pen and at the same time by using the simultaneous sampling of different channel circuit that can obtain a touch sensor data, systems and methods are provided. The digital I / O pins using an external passive filter components that may enable that is used to interface with the touch sensor electrode, is provided with a driving / reception circuit and method for driving and receiving a sensor signal electrode. A plurality of frequencies at the same time in the voltage follower Sigma adapted to drive and sense a touch sensor signal, the drive / receive circuits using the delta A / D converter is provided. The circuit may operate in a mode that detects a mutual, various combinations of the magnetic pen and touch signals at the same time. Capacitance multi-touch sensor is preferred, the circuit and method of the present invention is useful in many other types of touch sensors.
