The XW09B is a touch screen controller ICs SOP-16 RoHS manufactured by Sam&wing. It is used in sensing and controlling touch screen devices. This IC integrates the features of a capacitive touch screen controller in a single chip. It supports both self-capacitive and mutual-capacitive touch sensing techniques and also supports a multi-touch algorithm. Its main features include a high signal-to-noise ratio, low quiescent current, and low power consumption. It is also compatible with most MCUs and other common touch screen interface protocols, and features a low bit error rate (BER) for reliable operation. The XW09B has a built-in temperature sensor that allows for touch screen calibration and accuracy. Additionally, this IC is compliant with RoHS and REACH standards and is available in SOP-16 package.
