DATASHEET ISL29011 Digital Ambient Light Sensor and Proximity Sensor with Interrupt Function FN6467 Rev 6.00 May 1, 2014 The ISL29011 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function. For ambient light sensing, an internal ADC has been designed based on the charge-balancing A/D conversion technique. The ADC conversion time is nominally 90ms and is user adjustable from 11µs to 90ms, depending on oscillator frequency and ADC resolution.
