Integrated Optical Module for Smoke Detection data Sheet ADPD188BI. FEATURES GENERAL DESCRIPTION. mm mm mm Module with Integrated Optical The ADPD188BI is a complete photometric system for Smoke components Detection using Optical dual wavelength technology. The Module 1 blue LED, 1 IR LED, and 2 photodiodes integrates a highly efficient photometric front end, two light 2 external inputs for other sensors (for example, carbon emitting diodes (LEDs), and two photodiodes (PDs). These monoxide (CO) and temperature) items are housed in a custom package that prevents light from Three 370 mA LED drivers going directly from the LED to the photodiode without first 20-bit burst accumulator enabling 20 bits per sample period entering the Smoke Detection chamber.
