AS083 Industrial digital intelligent anti-interference

As083-ss1 is a CMOS integrated PIR (passive infra red) controller chip with low power consumption. Its internal structure
The frame is designed by mixed mode of analog and digital mixed circuit, which is very stable in all cases.
As083-ss1 adopts the third generation PIR human body thermoluminescence infrared detection technology scheme, with a built-in high-precision algorithm unit, which can be self-adaptive
At present, the environment, filtering out environmental interference, effective extraction of human signals, the farthest sensing distance up to 20 meters. The practical application circuit is quite simple.
R & D and production do not need debugging, greatly reducing production costs and saving space.
Product characteristics
· industrial standard, good stability, strong anti-interference, wide working temperature range, conducive to passing various certifications.
The built-in output PIR sensor reference voltage can effectively reduce the interference caused by the voltage change.
The built-in operational amplifier can be matched with a variety of PIR sensors for signal preprocessing.
The peripheral circuit of the built-in operational amplifier needs no debugging during R & D and production, saving development time and production cost.
The built-in high-precision algorithm unit can self adjust and adapt to the current environment, and effectively distinguish human signal and interference signal.
The sensing distance is far, and the probability of misoperation is far lower than that of traditional control chip.
Built in high-precision crystal oscillator.
· built in shielding time timer to effectively inhibit repeated misoperation.
The output delay time of control signal is adjustable, precise and wide.
External phototriode or photoresistor, not working during the day.
No load working current is small, power saving performance is excellent, suitable for battery power supply.
Special functions can be customized according to customer requirements.
The practical application circuit is quite simple, the consistency of mass production products is good, the repair rate is low, and the volume of finished products can be very small.
· sop8 packaging, small chip size.
· environmental protection packaging, not only meeting the EU ROHS standard, but also meeting the halogen-free green environmental protection standard (such as Sony SS-00259, apple
069-1857, Dell a00-00).
