The ADPD188BI is a complete photometric system for smokedetection using optical dual wavelength technology. The module integrates a highly efficient photometric front end, two lightemitting diodes (LEDs), and two photodiodes (PDs). Theseitems are housed in a custom package that prevents light from going directly from the LED to the photodiode without first entering the smoke detection chamber.
The front end of the application specific integrated circuit(ASIC) consists of a control block, a 14-bit analog-to-digital converter (ADC) with a 20-bit burst accumulator, and three flexible, independently configurable LED drivers. The controlcircuitry includes flexible LED signaling and synchronous detection. The analog front end (AFE) features best-in-classrejection of signal offset and corruption due to modulatedinterference commonly caused by ambient light. The dataoutput and functional configuration occur over a 1.8 V I2Cinterface or serial peripheral interface (SPI) port.
