QIs it possible for the AD7142 to be used with a touch glass ?
Is it possible to use the AD7142 for signature capture ?
AThe AD7142 can function through a certain thickness of glass (a few mm).
I assume that for signature capture, it is necessary to measure a 2d position
repeatedly to obtain an image of the pen trajectory. In this case the AD7142's
suitability would depend on obtaining sufficient resolution in the 2d space and
sufficient sample rate.
