ISL29030A

DATASHEET ISL29030A Low Power Ambient Light and Proximity Sensor with Intelligent Interrupt and Sleep Modes - Analog and Digital Out FN7722 Rev 2.00 November 12, 2012 The ISL29030A 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 sensor (ALS) data conversions, an ADC converts photodiode current (with a light sensitivity range of 2000 lux) in 100ms per sample. The ADC rejects 50Hz/60Hz flicker noise caused by artificial light sources. The IALS pin provides an analog output current proportional to the measured light (420μA FSR). For proximity sensor (Prox) data conversions, the built-in driver turns on an external infrared LED, and the proximity sensor ADC converts the reflected IR intensity to dig...
