Current Consumption
This comprises only the required initial dummy conversion cycle, NOT including the Analog part power-up time.
This value only includes the ADC and the driver switches, but it does not take into account the current consumption in the
touchscreen plate. For example, if the plate resistance is 200 ohm, the total current consumption is about 11 mA.
