CDPD188B is a highly integrated photoelectric detection module, integrating photoelectric measurement analog front-end (AFE), ADC, LED driver, timing controller, and FIFO functions into a single chip. It features 60dB high ambient light suppression capability, specifically designed for weak signal detection in complex light environments. Supporting multi-pulse integration and multiple conversion modes, it can output up to 24-bit effective data. As a system-level single-chip solution, it provides core support for the new generation of intelligent smoke alarm, air quality monitoring, and vital sign sensing devices.
