Description
AI
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.
