Keywords:proximity sensors? touch-screen? crosstalk?

This application note tackles the benefits of using the Maxim MAX44000 proximity sensors in handheld touch-screen applications. It then addresses a few application considerations. These include reducing crosstalk, improving noise immunity, and reducing the load on the application processor in the system. Sample C code for threshold hysteresis is available in the appendix.
