Integrated Circuits for Digital PIR ADCs
This comprehensive range of signal processor ICs provide cost effective solutions for various motion and gas detector applications.
The new generation digital detectors combine the sensor element(s) and the PIR signal processor in one package. The signal from the sensor element and the on chip temperature (= ambient temperature) are converted to digital values. An external microcontroller (µC) connected to the digital sensor via the serial DOCI (Data Out – Clock In) interface contains the software and therefore the functionality of the equipment.
All MOS products are CMOS based and manufactured and tested to the highest standards.
The new generation digital and smart detectors based on MOS integrated circuits eliminate the need for any analog circuitry.
