ADPD188BI-ACEZR7
Brand: Analog Devices
The ADPD188BI-ACEZR7 packs matched blue (470 nm) and IR (850 nm) LEDs with two photodiodes into a single 24-pin LGA_CAV optical module, forming a complete dual-wavelength smoke-detection front end. A 20-bit burst accumulator with up to 27-bit reads gives it the dynamic range to pick out faint smoke signatures, and an I²C or SPI interface drops straight into a smoke-detector or IoT host design.
