DATASHEET ISL29015 Integrated Digital Ambient Light Sensor and Proximity Sensor FN6522 Rev 0.00 October 31, 2008 The ISL29015 is an integrated ambient and infrared light to digital converter with a built-in IR LED driver and I2C/SMBus interface. This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation. For ambient light sensing, an internal 16-bit ADC has been designed based on the charge-balancing A/D conversion technique. The ADC conversion time is nominally 100ms and is user adjustable from 25µs to 100ms depends on oscillator frequency and ADC resolution. This ADC is capable of rejecting 50Hz and 60Hz flicker noise caused by artificial light sources.
