The present disclosure provides a selective data acquisition system of a matrix resistive touch panel and a method of using the data acquisition system to selectively acquire data on a touch panel. Each analog signal from the sensing track is tested with its own threshold value to determine whether the characteristics of the analyzed signal are sufficient to constitute a user's actuation on the touchscreen. If the analyzed analog signal exceeds or otherwise clears the threshold, the selective data acquisition system converts the signal into a digital word. Conversely, if the analyzed analog signal falls below or otherwise fails the threshold, the selective data acquisition system does not convert the signal. This process continues for all analog signals from the sensing tracks.
