APDS-9120 is an integrated optical proximity sensor that combines built-in signal conditioning and space-saving packaging technology. This optical proximity sensor provides ease of implementation as it eliminates design efforts required to implement external LED driver, signal filtering and amplification, sunlight and ambient light immunity, LED stuck high protection circuit. APDS-9120 is designed to be a robust optical proximity sensor. It has artificial light immunity and is also operational under the sun. Both analog and/or digital output options are available.
