Digital Output PIR Sensor Signal Conditioning Chip

The NSA3166 is a highly integrated signal processing chip for pyroelectric infrared sensors (PIR) for intelligent security applications. A single NSA3166 integrates all the necessary components for pyroelectric passive infrared mobile detection, and the analog front end can be directly connected to the analog PIR detector via AC coupling. Built-in high-precision analog-to-digital converter can convert the detector signal into digital signal. The digital engine can detect the movement of human body, reduce the interference from external and support binary output and digital output. The sensor sensitivity threshold and alarm maintenance time can be dynamically adjusted by writing registers through the digital communication interface. In addition, users can also configure and adjust the logic judgment mode of human body recognition inside the chip.
