This application report implements a Texas Instruments 4-wire touch screen controller (TSC) to control an 8-wire touch screen and discusses features and performances for such applications. Texas Instruments (TI) provides various TSC devices for the 4-wire or 5-wire touch screens (TS). A TI 4-wire TSC device, such as the ADS7843, TSC2003, or TSC2046, is ideal for controlling a 4-wire TS, but it can also be used on an 8-wire TS.
