DATASHEET ISL29028 Low Power Ambient Light and Proximity Sensor with Intelligent Interrupt and Sleep Modes FN6780 Rev 2.00 November 4, 2011 The ISL29028 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C Interface (SMBus Compatible).

This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel.

The flexible interrupt scheme is designed for minimal microcontroller utilization.

For ambient light sens
