The XW05B is a Touch Screen Controller IC manufactured by Sam&wing, and comes in a SOP16 package which is RoHS compliant. It is typically used in touchscreen displays and controllers. The IC supports up to 5 independent, simultaneous X, Y, and Z axis touch sensors, and provides functions such as on-chip signal gain control, advanced cross-talk manipulation, and multiple channels sampling. The XW05B also supports both I2C and SPI communications, as well as a variety of interrupts, making it compatible with a wide range of host electronic devices. In addition, the IC features an integrated, low-power A/D converter capable of delivering 16 bits of resolution with a sampling rate of up to 200 Hz. This makes it suitable for high-speed, sensitive touchscreen applications.
