The NCS36000 is a fully integrated mixed−signal CMOS device

designed for low−cost passive infrared controlling applications. The

device integrates two low−noise amplifiers and a LDO regulator to

drive the sensor. The output of the amplifiers goes to a window

comparator that uses internal voltage references from the regulator.

The digital control circuit processes the output from the window

comparator and provides the output to the OUT and LED pin.
