Ambient light sensors with auto gain switching capabilities

03/09/17 - 20170068303 - An ambient light sensor that is operable in high gain mode and low gain mode is provided. The high gain mode may help provide satisfactory sensitivity at low light levels but may generate saturated output levels in bright ambient lighting conditions. Low gain mode may therefore be switched into use
