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-b
