•
Low power consumption
•
~10mm switching distance
•
Factory calibrated, no calibration required in care
•
Pb free/RoHS compliancy
The proximity sensor works by sending out a beam of IR light, and then computing the distance to any nearby
objects from characteristics of the returned (reflected) signal. When the object is under 20 mm distance
detection will happen and output will go to high state (1.8V).
Touch screen controller
Touch screen controller for resistive touch pads contains a complete ultralow-power, 12-bit, analog-to-digital
(A/D) resistive touch screen converter, including drivers and control logic to measure touch pressure.
It also has embedded pre-processing function to reduce the output bus load. The host interface in TSC2004
is I2C.
