KEY PRODUCTFEATURES
It incorporates a highly accurate 12-bit ADC for data conversion and operates from a single 1.65 to 3.7V supply voltage. The SX8651 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
