Very low power Touch screen digitizer (Evaluation Board)

Question asked by LeNS on Jun 13, 2017

Hello,

I would like to record a subject finger touch. I need a very low current touch screen controller. The touch controller will be placed close to touch panel but far from the USB Interface and the acquisition PC (2-3m). I need to read and record in real time the touch coordinates  in matlab or python. I should scan an 8inches touch panel with a resolution less than 0.2mm in 2D. The electric current near my subject (so for touch panel and touch controller) should be less than 0.2 mA, but it can be more for the USB interface. I have no exerience in software/hardware in USB communications so I need a device very easy to use.  Do you have the other solution/suggestion? Any Evaluation module. I already have AD  Eval-AD7843 but the current consumption is high. 

Thanks
