DATASHEET ISL29033 FN7656 Rev 5.00 Ultra-Low Lux, Low Power, Integrated Digital Ambient Light Sensor with Interrupt September 28, 2016 Function The ISL29033 is an integrated ambient and infrared Features 2 light-to-digital converter with I C (SMBus Compatible) Ambient light sensing interface. Its advanced, self-calibrated photodiode array emulates human eye response with excellent IR rejection. The Simple output code directly proportional to lux on-chip 16-bit ADC is capable of rejecting 50Hz and 60Hz Variable conversion resolution up to 16 bits flicker caused by artificial light sources. The lux range select Adjustable sensitivity up to 520 counts per lux feature allows users to program the lux range for optimized counts/lux. Power consumption can be reduced to less than Measurement range: 0.0019 to 8,000lux with four 0.3A when powered down. selectable ranges The ISL29033 supports a software and hardware interrupt that Program interrupt feature 2 remains asserted until the host clears it through the I C Light sensor close to human eye response interface. The function of ADC conversion continues without - Excellent light sensor IR and UV rejection stopping after interrupt is asserted. 75 A maximum operating current Designed to operate on supplies from 2.25V to 3.63V with an 2 I C supply from 1.7V to 3.63V, the ISL29033 is specified for -0.3 A maximum shutdown current operation across the -40C to +85C ambient temperature 6 Ld 2.0mmx2.1mmx0.7mm ODFN package range.
