GENERAL DESCRIPTION
The SX8650 is an ultra low power 4-wire resistive touchscreen controller optimized for portable equipment where power and board-space are at a premium. It incorporates a highly accurate 12-bit ADC for data conversion and operates from a single 1.65 to 3.7V supply voltage. The SX8650 features a built-in preprocessing algorithm for data measurements, which greatly reduces the host processing overhead and bus activity. This complete touchscreen solution includes four user-selectable operation modes which offer programmability on different configurations such as conversion rate and settling time, thus enable optimization in th
