AN-2033 APPLICATION NOTE Calibrating the ADPD188BI Optical Smoke and Aerosol Detection Module
●The ADPD188BI is a complete photometric system for smoke detection using optical, dual-wavelength technology. The module integrates a highly efficient photometric front end, blue and infrared (IR) light emitting diodes (LEDs), and a photodiode, housed in a custom package that prevents light going directly from the LED to the photodiode without first entering the smoke detection chamber. The ADPD188BI is used with an EVAL-CHAMBER smoke chamber to create a complete, optical smoke detection solution for implementation in residential and industrial smoke detectors. The EVAL-CHAMBER is available for purchase with an order of the EVAL-ADPD188BI.
●This application note describes the calibration of the ADPD188BI using calibration coefficients that are programmed into the on-chip, nonvolatile memory (NVM) to reduce device to device variation to <+10%.
